With only the
initial submitted report and photos, I would be hard pressed to accept
this FOS record. But with the many subsequent excellent photographs and
numerous observers (including members of this Committee) and non-resident
birders who have come from several western states, this bird passes the
test beyond a shadow of doubt.
Let me one of the first to congratulate those responsible birders in
Washington County who found and identified this great new State bird. |

What a start to
2014!
This bird might be a HY/SY male bird based on the rectrice shape (Pyle fig
139b) in photo T, the extent of black on the top side of rectrices, and
the black lores and bib. |

Based on the documentation provided, there's nothing which would cause me
to not accept this as a Slaty-backed Gull. However, I look forward to
reviewing other's comments and further discussion in the second round. |
2nd round: |
26 Apr 2014 |
No, ID |
After reviewing the
comments of others and carefully re-reviewing the record, and also
checking additional internet/book resources, I'm changing my vote. This is
a difficult bird to ID and the possibilities of a hybrid are hard to
ignore. Although this could still be a Slaty-backed, I now have doubts
about this identification. |

Ryan has done a masterful job of elucidating the differentiating marks on
this bird. Obviously it is difficult for someone like myself who has no
experience with this species to offer any additional commentary. I have
reviewed also in detail the features of all the potential confusing
species in "Gulls of the Americas" by Steve Howell and Jon Dunn, and this
really does appear to be a first cycle Slaty-backed Gull. |
2nd round: |
2 May 2014 |
No, ID |
Given the fact that
even the experts have trouble with this identification, and all the
questions that have arisen with regard to this bird, it seems
inappropriate to accept this bird as a first state record and I am
changing my vote to no. |

I think several
characteristics (bill color, gonydeal angle, overall shape, long neck, leg
color, greater covert pattern) favor a Slaty-backed Gull and several
others do not (longish bill, gape shape, long wings, large primary panel,
inner primary web pattern), and still a few other important characters
cannot be addressed in the photos (tail and rump pattern, upper wing
pattern, secondaries, etc.). However, I don t believe any of that is
definitive either way, as I ve come to the conclusion that given current
knowledge, first cycle SB Gulls cannot be safely separated from hybrid
Cook Inlet Gulls (Glaucous-winged X Herring Gull hybrids) in NA. I studied
a first-cycle gull at Quail Creek SP in the winter of 2008-2009 that was a
very good candidate for a Slaty-back. I watched it for a couple months,
took dozens of photos in flight and various postures, and consulted with
many gull id experts. Several folks liked it as a Slaty-back but most
suggested it might also be a hybrid.
The consensus among experts is that first-cycle Slaty-backed Gulls cannot
be safely separated from primarily Cook Inlet , but also Olympic / Puget
Sound , etc hybrid gulls in North America (in the absence of newly molted
dark mantle feathers The California records committee has accepted a
couple late first-cycle Slaty-backed Gulls that show these fresh mantle
feathers). There has been extensive discussion among gull experts of this
identification problem over the years on ID Frontiers. However, there is
certainly no consensus on definitive identification characters to date. I
think Alvaro Jaramillo summed it up well when he recently replied to this
question on ID Frontiers (01/08/2014) you are absolutely correct in
suggesting that most Slaty-backs in first cycle will go unidentified, as
we have no way of eliminating hybrid possibilities. |
2nd round: |
17 Apr 2014 |
No, ID |
As stated in
first-round comments, this appears to a hybrid gull. While this bird shows
a few characteristics consistent with (and a few others suggestive of) a
Slaty-backed Gull, there are no definitive characters in the photos or
description that are diagnostic for a SB Gull. All of the suggestive SB
Gull characteristics are frequently expressed on hybrid gulls. There are
currently no definitive characters for distinguishing an early first-cycle
Slaty-backed Gull from a more probable hybrid. |

Most experts agree
that a first-winter Slaty-backed Gull is difficult to identify because at
this age they are variable and many resemble other immature gulls such as
first-winter Glaucous-winged Gulls, Vega Gulls and Herring x Glaucous-winged
hybrids. However I think there are a number of characteristics identified
by the observer, seen in the submitted photos and noted in literature
review that make me believe this is a first-winter Slaty-backed Gull.
The greater coverts stand out with there solid brown color. Only the tips
show some brown and white barring. The head is nicely rounded and lighter
colored than the body. The exception to this is an area around the eye
that is dark. The eye is also dark. The bill is black and straight but has
a pale pinkish base most noticeable on the lower mandible. The bill does
appear longer in the review bird than in most other photos of similar
birds I have studied and I don't know if this is critical in species
identification.
The tertials are a solid dark brown with pale tips. Many photos I studied
of other first-winter Slaty-backed Gulls show an even broader pale tip to
the tertials. The secondary bar looks a dark brown, even darker than the
greater coverts. The secondaries should not contrast too sharply with the
greater coverts and I don't know if the difference in the photo is that
much.
The primaries are dark with small white tips in the folded wing. The
observer notes that they appeared blackish but were more of a very dark
brown. The photos seem to confirm this especially when the picture is
zoomed in. This is important for eliminating other possible species. The
trailing edge of the pale under-wing primaries show a dark edge. This
characteristic is caught beautifully in photos C and D
It is hard to tell about the tail from the photos and the observer states
it was not seen well.
There are morphological characteristics that support this bird being a
Slaty-backed Gull. The bird appears long- necked (especially in photo B),
the pink legs are short and the bird appears to have a potbelly.
All of these characteristics are good for Slaty-backed |
2nd round: |
2 May 2014 |
No, ID |
This has been a
difficult record for me to review. I voted to accept this record on the
first round because I believed an excellent case for an acceptable record
was made for a first cycle slaty-backed Gull. After reading other
reviewers comments and looking at similar reviews from Gull enthusiasts
such as Alvaro Jaramillo I am convinced there is too much uncertainty with
hybrid gulls that can show similar characteristics. As Rick points out
early first cycle gulls of this species cannot currently be safely
identified. |

I've gone back and
forth on this one! At first I tended towards a SBGU but the more I studied
photographs and read, the less convinced I've become. I think the reporter
did an excellent job in his comparisons with other candidates and hybrid
possibilities, however I do think the characters which supported SBGU were
emphasized and the problem areas not dealt with adequately.
Problems:
1. The dark coloration around the eye/face is usually much more prominent.
Often times this dark smug takes on the appearance of a mask, sometimes
with darkness well above and below the eye, with a lighter area in
between. This bird does have some darking around the eye but appears much
less.
2. Every guide and description lists a prominent pale edge to the primary
wing tips. Neither the narrative or photos address this.
3. The variability of the overall plumage coloration, lighter/darkness of
the head, neck "collar" prominence, and wing patterns.
4. The unmottled/solid bar greater covert wing pattern is the strongest
character supporting a SBGU. However, several photos I've seen show this
to be also found in some hybrids.
5. A better photo of the tail and rump area would have been helpful.
6. The dark wedges on the underside of the wing tips is hard for me to
visualize.
7. The hybrid problem creates a nagging suspicion.
When we commonly use terminology such as "most of the time," "tends to
be," "darker/lighter than most," it always raises eyebrows. But such is
the case with gulls, especially 1st years.
Since even "gullologists" try to stay away from these 1st year and other
(hybrid) problems, and since it would be our first record for SBGU, I
think we better take a long hard look before we jump. I'm anxious to see
what the other committee members think. |

I really don't have

20 Mar 2014 |
No, ID |
I'm voting "no" for
a variety of reasons. I look forward to a discussion and sorry for my
delay in voting on this record.
The observer did a good job to describe the bird (using the photographs)
and to compare it against other species and hybrids. There are key
photographs that would be helpful when reviewing a bird in this plumage,
especially ones that show the upperside (and underside) of the spread
primaries in-flight and a much clearer view of the tail, which
unfortunately are lacking in this case. Likewise comparison photographs
with other gulls and especially with the more common (and possibly
confusing) juv/1st Cycle winter plumage of a Herring Gull are also
lacking. I suspect the observer was also concerned about this, given the
attempts to relocate the bird.
The set of photographs submitted is small and from an unusual angle making
judgement of structure difficult.
There are few specifics that I will argue in this round but one, the
record rules out American Herring Gull by the presence of "solidly
dark-centered greater coverts." This is variable on HERG of this age class
and greater coverts similar to this record can be seen in figures 25A.40
and 25A.43 in the Howell Gull book.
The record indicates opinions were solicited, including these ..... Are
there additional opinions from experts that were submitted? If there are I
would like to read them. |

First off I don't have any experience with Slatey-backed Gulls. In My
opinion first winter large gulls are some of the most difficult birds to
identify.
The observer seems to have written a well thought out report and has a
couple of expert opinions that seem to agree with his determination of
Slaty-backed.
Over all I agree with most of the points made with the following
exceptions:
#2 Mentions smudgy streak of brown on cream that forms a vague collar
which I just don't see.
#6 Dark centered not patterned greater wing coverts not shown on Herring,
Thayer's or Glaucous-winged X Herring Gulls. Looking at many pictures on
the internet and gull books, it looks like many of the pictures are very
similar to this bird.
I can't say that this isn't a Slaty-backed gull but then I can't say that
it is either.
I would like to see this record go to a second round so I can see what
others are thinking. |
2nd round: |
12 May 2014 |
No, ID |
The more I read and
study photos of similar gulls the more convinced I am that first winter
gulls in this plumage are not identifiable due to all the different
hybrids involved. |

[For the purposes of my discussion, the gull guide photos I am
referencing are those found in "Gulls of the Americas" by Dunn & Howell.]
This could be a Slaty-backed gull, but I do not think the possibility of a
hybrid (most likely Glaucous-winged x Herring) has been eliminated. The
legs do not strike me as very bright red in the photos (certainly within
range of the hybrids shown in the guide). Likewise, the darkness of the
greater coverts is very consistent with the hybrids shown in the guide
(see photos H2.5 and H2.6), and so is the corresponding tone of the
primaries. |

If we only had better photos. This is obviously an adult gull and the

As a committee we frequently struggle with the Iceland/Thayer's complex,
and rightly so, because it's a tough species pair to sort out and there
are intergrades. I'd be surprised if this record didn't meet some
resistance, but despite the poor quality of the photos, I agree with the
submitter that the primaries are noticeably paler than expected for
Thayer's Gull. The record relies heavily on relative size, which can be
problematic. Howell & Dunn give total lengths of California Gull as 18-23
in., Iceland Gull as 19-24.5 in., and Thayer's Gull as 19.7-25 in.
Therefore, any given Iceland Gull could be larger or smaller than either
California or Thayer's, and size is not very helpful in telling Iceland
from Thayer's. Even at extreme ends of the size spectrum, a half inch is
not usually meaningful in field observations. I think the main question to
consider here is whether Thayer's Gulls, or any other gull, could have
pale eyes plus wingtips barely darker than the mantle. I can't think of
any combination likely to produce that arrangement, especially in the size
range described. |
2nd round: |
30 Apr 2014 |
Acc |
The wingtips as they
are described, and even as visible in the poor photos, are way too dark
for an adult Glaucous Gull of any size. The wingtips could perhaps match
some Glaucous-winged Gulls in tone, but the structure, size, and eye color
are all wrong for any Glaucous-winged Gull and most if not all hybrids.
The main issue remaining for me is whether a light Thayer's Gull can be
eliminated. As an adult, even the lightest Thayer's Gulls have wingtips
that approach black (maybe "charcoal" or "dark slate"). Iceland Gull
wingtips range from the same slaty blackish color to almost pure white. So
regarding wingtip color, can we be certain these are lighter than "dark
slate"? From the photos, probably not. But the written description is
probably more reliable, and describes the wingtips as "nearly the same
color as the mantle", which is not the case for even the lightest Thayer's
Gull adults. Eye color on its own is not diagnostic, given that about 10%
of Thayer's Gull adults have a clear yellow iris (per Sibley), but lends
weak support for Iceland. As discussed before, size is not diagnostic,
with a wide range of overlap between California, Thayer's, and Iceland
gulls. Therefore, in eliminating Thayer's Gull, eye color is not
diagnostic, and size is not diagnostic, so we are essentially left with
the written description of the color of the primaries and as much as we
can deduce from the photos. This doesn't feel like much to go on, but I
still feel it is sufficient given that we have narrowed discussion down to
Thayer's or Iceland. The primaries are simply too pale for any adult
Thayer's. I could be convinced to vote no if I could come up with a hybrid
combination that would give a body size in this range and a wingtip this
color, but the only combinations I could come up with are really out
there, perhaps never documented. |

While I voted to accept this record in the first round I now have doubts
if a pale Thayer's has adequately been considered. The photos are just not

enough to make a convincing case for Iceland Gull. We all know how

photographs are not sufficient for an unambiguous identification. |
2nd round: |
17 May 2014 |
No, ID |
The photographs show primary tips darker than the mantle and the observer
describes the wingtips as being "one shade darker than the mantle".
Unfortunately, the subtleties of this comment cannot be appreciated with
the photographs provided nor with the written description. I don't believe
we can say with certainty that the primaries are too pale for a Thayer's
Gull especially given the sun conditions that produced photographs with
significant glare; I suspect the observer's view of the gull was affected
in the same way. |

I don't have any
problem with the eye color, as I've observed several apparent Western
Gulls with similar eyes (similar to the 2nd cycle gull in the Cornell link
provided by David). I also don't think the bill is 'too slight' for a
Western Gull; however, I also don't think it's out of range for a LBBG.
There have been many large (and large billed) dark mantled gulls observed
in the west in recent years labeled by experts as Lesser Black-backed
Gulls (although usually with some doubts). With that said, I still think
more characters point to this being a Western Gull. |

I feel a bit bad about this record. This was flagged for review in my
queue as the eBird reviewer for the region, and before I even looked at
it, I encouraged Mike to submit it to the UBRC for review. Then, after I
actually looked at the pictures, I realized it's not a Western Gull. As I
told Mike, the first thing to give me pause is that the eyes look really
pale. Western Gull eyes aren't always super dark, but this is paler than
I'd expect on most WEGU. The bird and its head and bill look large, which
would fit WEGU, but I don't get an impression of an especially thick bill
that would indicate WEGU. Finally, although it's always better to judge in
life than in photos, I feel like the mantle might be a bit too light for
WEGU. It's not so far off that I'd rule out WEGU on mantle color
alone, but in combination with bill shape and eye color, I'm just not
seeing a strong case for WEGU. I think this is most likely either a Lesser
Black-backed Gull or perhaps a Lesser Black-backed Gull hybrid. On the
Facebook North American Gulls page, several well-known gull experts
supported the identification as a Lesser Black-backed Gull, including
Steve Hampton and Amar Ayyash, although others suggested various hybrid
combinations. None suggested the original identification as Western Gull
was correct. |
2nd round: |
30 Apr 2014 |
No, ID |
The bright pale eye
and "black eye" look (concentration of dark feathering around the eye)
still have me leaning strongly to Lesser Black-backed Gull or LBBG hybrid.
I also see a low sloping head, rather than the peaked, rounded head of
Western Gull. In response to Dennis's question about the reference to the
"Salt Lake County review species list," I'm pretty sure the observer is
referring to the records that are flagged for further review in eBird
(filters in Utah are set at the county level). I think the discussion of
this bird from the North American Gulls Facebook group that I referenced
in the first round is quite helpful in considering this record, and
several of those participants are much better than I am at gull
identification. For the committee's reference, here is that conversation
about Mike's photos. It is worth noting that no one here suggests Western
Gull:
Steve Hampton: Lesser Black-backed Gull? Got more pics?
Amar Ayyash: I'd
agree with 2nd cycle LBBG.
(Mike Hearell posts a few more photos)
Andrew Baksh: Agree with votes for 2nd cycle LBBG.
Chris Hill: I saw it, I thought "whomping big Lesser Black-back." I
would love to be corrected and find that some mid-Asian stray looks like
this, but so many things that look weird in that particular way turn out
to be LBBGs in the end.
Paul Budde: That bill does look quite large and swollen for LBBG, even
accounting for the fact that darker colors (like the gonydeal angle) look
larger than there are.
Noah Arthur: YES, there IS a mid-Asian stray that looks like this! The
bill on this bird is huge. The size being "larger than the Herring Gull"
seems WAY too big for LBBG. My vote is for Heuglin's Gull. [RPO note:
currently considered a subspecies of Lesser Black-backed Gull]
Mike Hearell: My concern with this being called a LBBG is the fact that it
has PINK LEGS (much more visible through scope than camera) and was MUCH
LARGER than the surrounding HEGU [RPO note: HERG] and CAGU. Most LBBG I've
seen have been slightly larger than CAGU and a hair smaller than HEGU [HERG].
I know the younger gulls plumage makes them appear larger than they are
but the size difference in this gull was quite noticeable.
Steve Hampton: Can we rule out Herring x GBB[G], which would seemingly
explain both size and leg color?
Martin Reid: Chris I'd say that "so many things that look weird" are
ASSUMED to be LBBGs - I'll bet that there is not a single one where a
band/ring or genetic data has proved the identity. There has always been
the danger of circular reasoning in this issue, and I caution us to
remember than almost all IDs are conclusions - they are not proven.
Noah Arthur: Looks very long-winged for HerringXGBBG. Follow him until he
sings, and get a recording of the song! The song of Heuglin's is
noticeably lower than LBBG, according to Olsen and Larsson's book (I did
this with a bird in San Leandro last winter, which turned out to be LBBG).
Noah Arthur: Yes, I certainly think that many birds are ASSUMED to be
LBBGs with no real proof -- there have been some really big-billed
individuals here in CA that really might be something else...
Noah Arthur: The only other thing I can think of might be LBBGXGBBG. Are
there any records of that?
Martin Reid: While we are speculating, what about Kelp hybrids? I gather
that after a Katrina-induced hiatus, Kelps (or residual Kelp hybrids?) are
breeding with American HERGs some where east of Louisiana... Offshore
islands in Alabama, maybe?
Amar Ayyash: I want to make a couple of points without sounding too
stubborn about this being a LBBG.
I wouldn't worry about pinkish legs on a 2nd cycle Lesser. 3rd and even
4th cycle types are regularly recorded with sub-adult pinkish legs. As for
size, I (on rare occasion ) find Lessers that tower over surrounding
Herrings. Giants? Not uncommon is to see one that's more or less the same
size as Herrings, presumably males. LBBG is not very rare in Utah, and
there shouldn't be an expectation that they're all going to be slim-bodied
and smaller than Herrings.
With that said, I'd like to see more photos of this gull before I place my
bet.
Mike Hearell: [posts another photo of the same gull]
Amar Ayyash: Consider this individual, Mike:
http://www.gull-research.org/lbbg3cya/w0nj.htm
Maarten van Kleinwee: It amazes me how quickly the hybrid option is raised
in this FB group each time a gull doesn't fit a box perfectly.
Mike Hearell: It's true that LBBG are becoming more and more regular in
Utah and it was just recently removed from the review list. My comments
about leg color and overall size were more of a question about variables
within the species than a statement that it is not said species.
Amar Ayyash: Sorry for the quality of this video, but here's a similar
looking LBBG that I recorded in Chicago a couple of years ago. It was a
beast, matching and even exceeding the size of some of the surrounding
Herrings. It dominated the beach for the couple of hours it was there.
http://youtu.be/ysIyVlYjvwI
Aaron Brees: Martin, there was a big debate several years ago over the ID
of a dark mantled gull in Missouri with a lot of the discussion leaning
toward Kelp or Kelp hybrid as many felt it was too large and robust to be
LBBG. It was very controversially collected and proved to be a LBBG by DNA
if recall correctly. So, that's one anyway.

I've read the

Among other features, the size and structure are convincing, the large
bill, the leg color, and the mantle darkness all fit well with western.
Some note the eye as being too pale for a western of this age but this
field mark is variable but still within the expected range for this

You know, I fully sympathize with the argument that any gull could be a
hybrid, but in this case the size is just so impressive. And I am troubled
by the shape of the bird, which does very much remind me of a LBBG. On the
other hand, to address some of Ryan's concerns, the color of the face and
eyes look very much like the 2nd cycle bird in the Cornell site, All About
Birds:
http://www.allaboutbirds.org/guide/western_gull/id
In fact, that bird is nearly a dead ringer for this one except for the
thickness of the white band at the end of the tertials.
The thickness of the bill, especially the gonydeal angle, so unlike the
LBBG, is what I find most convincing in the end. |

This may well be an American Black Duck, but I am not totally convinced
that Mottled Duck has been eliminated. The bill color appears to me to be
more yellow than dull yellow-green, and the head color seems more
consistent with Mottled. Mexican Mallard I feel also should be considered,
although if there really was no white at all bordering the speculum that
seems less likely. The back certainly is very dark, most consistent with
American Black Duck. I would like to see what others say on the first

one of the furthest north Mexican Ducks recorded to date. |
Ryan O. |
21 Mar 2014 |
No, ID |
No attempt was made to eliminate other dark Mallard relatives, including
Mottled Duck and "Mexican" Mallard. The absence of any white bars on the
wing should rule out Mexican Mallard, assuming a thin white edge would be
seen if it had been present, but many Mottled Ducks have essentially no
white on the leading (proximal) edge of the speculum, and only a very thin
white trailing (distal) edge would be easily lost against a light
background. The comments that, "The bill color was a dark yellow color and
not orange like the hen Mallard" and "It was not a drake Mallard based on
lack of green head" also indicate that Mexican Mallard may not have been
considered, since hen Mallards of the Mexican subspecies don't have an
orange bill and drake Mallards of the Mexican subspecies don't have a
green head. I don't feel that Mexican Mallard or especially Mottled Duck
were sufficiently excluded in the written details, and I think that range
isn't sufficient to rule either!
of these out since there have been several records of Mexican Mallards or
intergrades in Utah in recent years and there are Mottled Duck records
from Colorado and Wyoming.
(25 Mar 2014) The photos are a very helpful addition
and at least rule out Mottled Duck (given the lack of a black spot at the
base of the bill). However, given the relatively warm buffy tone to the
head and the warm buffy flank streaks, not cold grayish in each part, plus
the amount of white visible in the tail feathers, I still feel this bird
is not consistent with (pure) American Black Duck. My best guess is mostly
"Mexican Duck" (Anas [platyrhynchos] diazi), with a bit of "Northern"
Mallard introgression making the tail whiter than it would be
otherwise, but I'm not confident ruling out all American Black Duck x
(Northern) Mallard hybrids either. |

I went out to the same spot where this record was reported and am 99% sure
I saw the same ducks (pair) referred to in these reports. I therefore,
perhaps, may have a bit of a bias. Let me just say that this would be a
Utah Lifer for me, though I have seen the species back East.
I do not think this is an American black duck for three main reasons:
1) These photos strike me as unnaturally dark & saturated, especially when
you compare the tones & darkness of the flanks to the head on the male
(the face should be much paler compared to the flanks on a black duck).
The ducks I saw were paler in real life, and this insufficient contrast
was what broke my lister heart in the field.
2) The pattern of the flank feathers isn't right for a black duck. The
duck in those photos has far too much pale edging to the feathers, and the
edging is dull tan rather than rufous.
3) There seems to be an awful lot of paleness to the upper tail for an
American black duck.
I noticed all these field marks in the field, but they are visible in the
photos as well. I am not sure what this is, possibly some Black duck x
Mallard hybrid or perhaps something with diazi ("Mexican duck") genes. The
Mallard superspecies is not well differentiated to begin with, anyway.
I hope y'all can talk me out of my vote, as I sure wouldn't mind another
Utah lifer, but right now I just don't see this as a pure American black
duck. |

Anything supposedly can turn up anywhere, but this would be a real

of several other possibilities for confusion. For a first state record, we
need much more convincing proof than this. Fourteen years can is a long
time for memory to accurately reflect on what was seen, especially when
the observer did not have bins. Oh for a photograph. In spite of all that
I have said, somewhere in the back of my mind I really wonder if her

My biggest concern with this record is that the observer initially
thought it was an Abert's Towhee. It is quite a stretch to think of these
two as similar species. It doesn't help that the observer didn't even
bother to look it up until five days later, and the notes presented here
are from memory fourteen years later. Reporting the sex and age as an
adult female (when first year males look almost identical) further
indicates that this might be a record that over-presents its confidence.
The description isn't a great fit either: I think of this species as being
more robust and bulky than an American Robin, not more slender. Head is
described as "darker" but the blackish cap is not mentioned. Overall, I
have too many concerns about this record to accept, especially given that
it would be a first state record. |

I am not sure how to handle the two Rose-throated becard records (2014-008
& 9). The species just doesn't occur anywhere near Utah and is not on the
Nevada, Colorado, or Idaho state lists (I can't even find it on the New
Mexico list, although I may not be looking in the right place!!). In
Arizona it occurs only in the very SE corner, barely spilling over from
Mexico some years. And then two show up in St George at one time, yet not
together? Seems highly improbable.
To make things worse, the observer didn't have any experience with this
species and described the female as scratching around on the ground
(uncharacteristic for a becard, to say the least). The birds were not
observed with binoculars or scope, no field guides in the field, no notes
were taken in the field (other than mental), and the mental notes were
written down much later.
I think we need more than this for a state first. |

I'm still quite
conflicted on this record. I can't find anything in the record that rules
out Rose-throated Becard, and a male would be quite distinctive. The
record of the female was far more concerning, but I think each record
should be judged on its own merits. I trust the observer's memory of such
a distinctive and remarkable sighting - there are a few birds I could
still describe well from memory 14 years later because they made such a
strong impression on me. To be completely honest, given the level of
rarity, the time since the observation, and the lack of corroborating
evidence such as another observer's report or photos, if I were the
deciding vote, I would vote "No." But since this record has already been
rejected (six "No" votes have been received), I'm voting "Yes" in part as
an indication that the only real concerns with this record are the gap in
time and the lack of other observers or physical documentation. |

While the description certainly sounds like a likely candidate for a
Rose-throated Becard this species is extremely rare North of Mexico. It
also has been a very long time since the bird sighting. The sighting of a

Adult female Red-naped Sapsuckers can have an all-red throat completely
bordered by black, and no red on the nape. Those two traits alone are not
sufficient to distinguish a male Yellow-bellied Sapsucker from a female
Red-naped Sapsucker. We can't see the back pattern, and the observer made
no attempt to describe it. Also there was no attempt to eliminate
potential hybrids. |
2nd round: |
7 Jun 2014 |
Acc |
The written description is of little help, describing only two field marks
and not attempting to eliminate any other sapsucker or hybrid. Thus, we
are left with only one obscured photo to judge. I don't see any red in the
nape, and the throat (or as much of it as can be seen) appears completely
red with a complete black border. These are good indications of
Yellow-bellied Sapsucker, but they are not sufficient on their own. As
pointed out in the big Sibley, adult female Red-naped Sapsuckers have the
"nape usually red, sometimes white," and a "white chin; sometimes all-red
(such birds very similar to male Yellow-bellied)." The completely red
throat of some female Red-naped Sapsuckers is discussed at length in
Leukering 2007, "Sapsucker identification: the problem of female Red-naped
Sapsuckers with red throats," Colorado Birds 41:292-294. Leukering also
mentions that female Red-naped Sapsuckers can have no red on the nape.
However, the presence or absence of a red nape patch in Red-naped
Sapsuckers is not random with respect to season. Leukering 2007 indicates
that all Red-naped Sapsuckers in fresh plumage have red on the nape, and
that when the red is absent, it has been lost due to wear. Similarly,
Mlodinow et al. 2006 state that, "Red-naped Sapsuckers lacking red on the
nape between October 1 and May 1 [when the plumage is fresh] would be
exceptionally unusual, if such occur at all." Thus the lack of red in the
nape on this bird in March is a more reliable indicator of identification
as Yellow-bellied Sapsucker than I had realized.
The facial pattern on this bird appears more white than black, which is a
good (if subjective) indication of Yellow-bellied Sapsucker over Red-naped
Sapsucker.
Although the back is almost completely obscured, the amount of white on
the tertials corresponds well with the amount of white on the back, and
this bird has a very large amount of white visible on the tertials, more
than I've seen in Red-naped Sapsuckers and even more than many
Yellow-bellied Sapsuckers. |

The white stripes
that go through the face are as broad or broader the the black stripes and
red throat seems to be completely bordered by black. These characteristics
support a Yellow-bellied Sapsucker. I have concern however with what
appears to be a tinge of red in the nape area which is dark. I also cannot
determine the extent of white streaking in the back from the supplied
photo. The narrative does not give information on these details. For the

I am not entirely sanguine about whether the Yellow-bellied
sapsucker is a separate species from the Red-naped, but, assuming it is,
this seems like a bird pretty far down the cline toward the former. Most
reputable sources hedge their differentiating field marks (nape spot,
throat border, back pattern, etc.) with words like "usually," to drive
that point home. But this bird's markings strike me as Yellow-bellied.
Irrespective of which bird it is, what a lovely individual. |

Although this would be a first state record, the observer is "familiar
with the species." Even though the time of observation was short, I
believe the observer adequately identified the bird in that time frame
because of his experience with this species. |

This is an excellent description by the world's expert and I have no

well have been a Mississippi Kite, and I have been made aware of other
possible sightings, and I would not be surprised if this bird was more

Excellent description and sketch. A second observer was able to see the
same bird roughly 20 miles further north the same day:
http://ebird.org/ebird/view/checklist?subID=S18233934 It is quite
interesting that this observation was within one day of the bird Craig
Fosdick and I saw on 5 May six years earlier (see
record 2008-08, which was
not accepted). Perhaps that record will be worth re-evaluating in a few
more years when (if?) a pattern of Mississippi Kite vagrancy is better
established. |
2nd round: |
7 Aug 2014 |
Acc |
This record has
already received more than six "Accept" votes in the second round, and so
has been accepted, according to section IV.C.10.b of our bylaws: "Voting
on a second-round record ends as soon as 6 votes to accept or 6 votes to
reject have been cast." But since it's still on the voting table, I'll add
my notes anyways.
Two members mentioned that the record should be accepted as "provisional"
in their votes. Our bylaws IV.C.11 states, "Accepted records will be
listed as either 'verified with physical evidence' or 'accepted but not
verified with physical evidence.' First state record submissions that
involve only a single observer, may be accepted as 'hypothetical' and
added to the UOS Checklist of Birds of Utah as such. Species shall remain
on the hypothetical list until a record meeting the above criteria is
accepted by the committee." Like several parts of our bylaws, this is a
bit ambiguous. How is it decided whether a record meets the "physical
evidence" criterion? By vote? I think the sketch included in this record
qualifies as physical evidence, but I could see the logic in arguing that
it does not. What does it mean that a record "MAY be accepted as
hypothetical" (emphasis added), and if it MAY be accepted as hypothetical,
who decides that it IS hypothetical? While there is much room for
interpretation, I read these bylaws as meaning that a record is only
"ACCEPTED AS HYPOTHETICAL" when 1) only one observer submits a record, 2)
the species is not obvious or easy to identify and can be confused with
similar species, 3) the observer is not familiar with the species, 4) the
observer is not known by the committee to be a careful competent observer
with experience, AND 5) there is no physical evidence. I don't think we'd
EVER vote to accept a record under those conditions (i.e., when the
observer is unknown, the species is difficult, there is only one observer,
and the observer is not familiar with the species). This makes the
"hypothetical" list, if I'm understanding it correctly, a bit of a moot
issue.
The term "provisional" doesn't appear in our bylaws, but it does appear in
our checklist. Conversely, "hypothetical" doesn't appear in our checklist,
but does appear in our bylaws, so I suppose we are using these
synonymously. In practice it seems that "hypothetical records" are records
that had no "physical" evidence and only a single report filed (even if
there were multiple observers). In conclusion, although I still think we
need to tidy up our rules at some point, it seems in practice that whether
this record is "provisional"/"hypothetical" depends only on whether a
sketch counts as "physical evidence," and that decision is probably left
to the secretary and/or webmaster. If it matters, I vote for this as a
"full" acceptance, i.e., not on the provisional/hypothetical list. |

First let me make it
clear that I'm 99.9% sure we have our first Mississippi Kite record for
Utah. As luck would have it, the bird flew over one of the best qualified
people in the State to ID it correctly.
Certainly very few field birders in this State are more familiar with
raptors in flight than this reporter. However, If you or I saw this bird
and were convinced enough to turn in the record as a Miss. Kite, there
would be a high possibility of its rejection, and probably rightfully so.
Unless there was "preferably" additional substantiating physical evidence.
So here we face the problem. We who know the reporter, know that he is a
competent observer, very familiar with this species (and all other
raptors), and thus easy for him to ID. Unluckily, no other observers were
present and no physical evidence was possible. His report is certainly
noteworthy.
Maybe this is a record that should be recorded as provisional. I'm anxious
to see the Committee comments. |

Ok, I thought
I might be the only one who would vote against this record the first go

problem where once again we can't help but be swayed by the one who
reports the bird. It's true nobody I know would be more qualified to
document an unusual bird of prey for the State than the reporter. But what
about the rest of us? I vote to accept the record as a provisional
species. |

Not sure of the ID based on the description. The color descriptions "very

There are several things about this rather brief description that concern
me. It is hard for me to think that an Orchard Oriole could ever be
described as orange. It is really a deep chestnut. In the similar species
description, the one obvious confusing bird would be a Baltimore Oriole
and that is not even mentioned. I am perplexed by the description of the
tail as all black, which suggests Orchard, not Baltimore. But I have

The size is described as the same as an American Robin, but an Orchard
Oriole is significantly smaller than that species, then later it is
described as the size of a bluebird or a robin, which is a considerable
range of sizes. The head is described as black "down to the nape of its
neck" but this is not consistent with Orchard Oriole, which should have
the black continuing not just to the nape but also down the entire back. I
can't quite fit this description onto any other expected species, but it
is not consistent or thorough enough in my judgement for a second state
record. |
2nd round: |
8 Aug 2014 |
No, ID |
I can see David's
position that this is likely just an imprecise record of a real Orchard
Oriole. There aren't any species that I think this record fits better than
it fits Orchard Oriole. But there are enough inconsistencies or points of
imprecision for me to have significant doubts overall. Those doubts might
not be enough to convince me to vote against the record if this weren't
the second record for the state, but given the rarity of this species, I
hold the records to an accordingly higher standard. |

It seems we all had
the same questions about this bird on the first go-around (crimson?
Baltimore? size?) and some considered these enough to reject and others

either way, by "Avian Biologist."
It's a close call but I concur that specific oriole ID was not completely

The description of
this bird is not sufficient to rule out other species such as Baltimore

30% shorter in length, and half the wingspan. |

Although the description of the bird's undersides as "crimson red" is a
bit different than my (and Wikipedia's) understanding of that color, I
will chalk that up to individual terminology. I cannot think of anything
else with the described field marks. The observer's status as an avian
biologist helps in the credibility of the report. |
2nd round: |
29 Jul 2014 |
Acc |
One would think that an obvious bird like the Orchard oriole would be easy
to describe, especially by an avian biologist. Odd that more care was not
taken to describe the bill shape as decurved, and the extent of the head
blackness is imprecise (but no better indicative for a Baltimore oriole,
which also has a black back).
And the underside color description is just plain unfortunate. I assumed
in my 1st round vote that it couldn't have been orange-yellow of a
Baltimore oriole because the observer specifically stated it was not the
color of a Bullock's.
To those troubled by the size comparison to the American robin, one should
note that a size range was given, from bluebird to robin, so that
shouldn't disqualify this sighting. And the description of the tail as
solid black should eliminate the Baltimore and support the Orchard, though
I suppose the orange-yellow might have been missed. All in all, this is an
imperfect record. I am more on the fencepost about this one than this bird
itself was reported to have been.
Still, I feel this is an unfortunately vague and odd record of an Orchard
oriole. |

I have had a great deal of trouble pulling the trigger to vote on

description is good for a Pine Warbler. I am disturbed by the suggestion
it could be a juvenile. What would a juvenile be doing here this time of
year. If a juvenile would be considered, then one would have to consider
both Bay-breasted and Blackpoll Warblers. The bottom line is that I don't
believe this was a juvenile, but probably an adult female. If this were a

This is a bit of a
"heartbreaker," a very rare bird that in my (revised) opinion is very
probably an authentic sighting but just doesn't quite make the cut.
Although there are no convincing contenders for the identification of this
bird (I find the description of a plain back without streaks to be
sufficient to rule out Blackpoll and Bay-Breasted), I can see the issues
others have mentioned with the description of the eye ring ("complete"
versus two arcs), sides of breast ("yellowish wash from bottom of throat
through mid breast and sides" versus faintly and subtly streaked), "undertail"
described as completely white (this is ambiguous, although I had
interpreted it to mean "undertail coverts, not including retrices"), and
the mention of a possible "juvenile." As Dennis mentioned, I have added
confidence in this record given the experience of the observers and the
fact that multiple other observers confirmed the identification. However,
much like the Orchard Oriole record we are currently considering, this one
must meet a higher standard of scrutiny given its rarity in the state, and
I agree with others that it doesn't quite meet the bar. |

This may be a valid

I had to take a long
look at this record. I could go either way. Warblers, especially female
(immature) are always problematic. The fairly detailed report which
covered four or five of the key characters, the long look , the previous
experience with the species, and the other birders who independently saw
the bird were the facts that barely tipped the scales (for now). A few
photos would sure have helped. |
2nd round: |
13 Aug 2014 |
Acc |
I again took a hard
evening's look at this record. I read and reread every ones comments, went
back over the submitted report, studied warbler books and even went back
and read the first record entry. I think the recorded characters narrow
down the possibilities to those species mentioned. But, remember this is a
spring time bird, and most likely in adult plumage. Take a look at
our YOS record and the photos submitted. I think the current submitted
record pretty much describes these photos. Even the "faint cream, complete
eyering, appears that way in the photos. Maybe "complete" was a poor
choice of words. Like me, I'm sure you think the same way as I do when you
hear "complete eyering" -- a bold, prominent white circle around the eye
like a Connecticut or Nashville Warbler. But a faint eyering is harder to
imagine. With the described back lacking streaks, grayish auricles, white
undertail(coverts?), two wing bars, thick, dagger-shaped bill, prior
experience with the species and other additional independent observers, I
still think it warrants acceptance. |
Jack S.
2nd round: |
2 Aug 2014 |
No, ID |
This description
fits a female Pine Warbler quite well with a couple of exceptions.
(1) As pointed out by Kathy, the eye-ring is described as complete;
this species 'eye-ring' comprises an upper and lower arc surrounding the
eye. The arcs are separated by a relatively faint dark line extending from
the lore to the back of the eye. This is relative easy to observe on this
species, especially at close range.
(2) The observer also indicated the 'Undertail was completely white';
this species undertail coverts are white as is most of the underside of
the tail, however there is also a thin black border around the undertail
coverts and also thin black edges near the tail tip.
The first state record for Utah (2007-46) sets a high bar for this
species and this record (only the second state record of Pine Warbler if
accepted) is not nearly as well documented. |

I am very inclined to believe this was indeed a Pine warbler, but I'd like

marks presented fit a Pine warbler best, but I am not satisfied that other
species (esp. Bay-breasted and Blackpoll warblers) have been adequately
addressed. The back color & streaking come close to satisfying this
concern for me, but it seems this can be a subtle distinction, and the
streaking in these can be nearly non-existent. |

I consider this to have been submitted as a record of "Mexican
Whip-poor-will." Given the observer's experience and the written
description of the song, I think this is marginally acceptable as an
unidentified Whip-poor-will species. Common Poorwill is described as
having a "two-whistled note" but I think at close range the song of the
Common Poorwill is closer to three syllables, "Poor-WILLip." Eastern
Whip-poor-will is only eliminated by describing this song as "more reobust"
[sic], but given that "robust" can have various meanings and could be
affected by volume, I don't fell this is sufficient to eliminate Eastern
Whip-poor-will. |
2nd round: |
8 Aug 2014 |
Acc,NAS |
The record says that
the song was "compared in field with iBird Plus" but it doesn't say which
songs were compared, or whether Eastern Whip-poor-will was played. The
entire distinction in this record between Eastern and Mexican
Whip-poor-will lies in a single word, "reobust." No further description,
details, or evidence is provided to eliminate Eastern Whip-poor-will. As
with two other records we are currently considering, this would be only
the second state record. I just don't feel confident hanging a second
state record entirely on a single word in a written description from a
single observer. It's really too bad the observer didn't make a recording
with the same iPhone he used to broadcast the call. |

The main reasons I don't believe this is a Yellow-bellied Flycatcher are:
1) The eyering appears white with narrowing at the top and some of the
photos show a widening behind the eye. This seems more consistent with a
Western Flycatcher than a Yellow-bellied. 2) The primary tips show a wide
gap between p4 and p5 (of the visible tips) which would indicate a Western.
3) The head shape appears slightly squared off at the back. Although it is
not really peaked like a Western, it is also nor really rounded like a
Yellow-bellied. 4) The coloration of the wings and back appear dull and
less contrasting than a typical Yellow-bellied. The back color seems to
have an olive brown tinge, and the wings appear dark brown rather than
black which supports a Western as opposed to a Yellow-bellied. |

I am having difficulty with this bird. I cannot be sure if the photos from
the three individuals are all of the same bird. I feel fairly strongly
that the photos by Matt Pendleton are of a "western Flycatcher". If this
is the same bird that all three photographed I don't believe it is a
Yellow-bellied. The other photos are a bit more problematic. I believe if
one looks carefully at the eye ring, it is not a distinct complete eye
ring in most of the photos, and it is accentuated, at least in most of the
photos, behind the eye. This would suggest Western.
I have spent the summer at our cabin in northern Idaho on Priest Lake. We
have "Western Flycatchers" nesting in our yard. This particular bird this
year usually called with the Pacific-slope call note. I have spent
extensive time observing the parents and the young. To be honest, the
photos of Matt look pretty much Identical to the birds in our yard. At
least on the first round I am going to vote no. I do feel that all the
other empids can pretty much be eliminated. |

I believe this is a
Western Flycatcher based on the primary spacing; there is a much larger
gap between P5 and P6 than between P6 and P7 visible in full resolution
images of photos.
In addition the eye-ring appears thicker behind the eye and reduced above
the eye in several photos and the wings appears browner (less dark and
contrasting) with limited less contrasting tertial edging. |
2nd round: |

Primary spacing is the best mark for differentiating YB and Western
Flycatchers and is consistent with a Western Flycatcher in the photos. |

I believe the photos show an almond-shaped eye ring that is incomplete or
nearly incomplete on the top. The head also looks peaked and the bill
long. Each of these traits is consistent with a "Western" Flycatcher. |
2nd round: |

For the same reasons as the first round. It s fascinating to me how much
we can look at the same photos and come to different conclusions. I still

incomplete at the top, a peaked head, and a long bill. |

So many photos to
review with some very goods looks at the primary wingtip spacing. I think
the photos clearly show p5-p7 spacing of one large gap bracketed by two
smaller gaps which would indicate a western flycatcher and not a
yellow-bellied. |

I spent a morning on
this record. At first I thought here we go again, another borderline
Empidonax flycatcher. After once again reviewing all the guides, including
a very good section on Empidonax flycatcher identification in Advanced
Birding by Ken Kaufman, photos, and past records, I believe this record
justifies acceptance. I can find no real conflicting characteristic from
the photos or report. Granted the real problem is separation from the
closely similar, and much more common, Cordilleran Flycatcher. The nearly
complete, teardrop lacking eye ring, crestless, more rounded head, medium
length primary projection, slightly darker wings, more yellowish throat,
and bright orange lower mandible, all are consistent with a YBFL. Each of
these characters are portrayed in the sets of photos submitted. The shared
characters with COFL can include the yellowishness of the breast and belly
and makes this character less valuable in fall migrants and juveniles.
This would be our first accepted record, which makes for additional
scrutiny. |
2nd round: |
20 Nov 2014 |

I know this is a close call, and still believe it may be a Yellow-bellied

would be a FOS there needs to be a consensus. |

This is a difficult
individual (and species) to separate from the more common Cordilleran
Flycather. I'm voting a tentative yes however given the quality of the
photographs provided with the record.
The head is rounded without sign of a crest in any of the photographs
provided.
The wings bars and tertials are less contrasting with black than I would
expect on an YBFL but this bird appears hatch year.
The eye-ring is complete and has only a small rear extension in some
photos. The bill is consistent with YBFL. |

I believe it can be difficult to separate a "colorful" Cassin's from a
Blue-headed Vireo. One point against this being a Blue-headed is the date
as the Blue-headed, as I understand it, migrates later than this as a
rule. However I agree that the description and the photos strongly suggest
Blue-headed. In addition to what is stated, the wing bars are definitely
yellowish and they should be white in a Cassin's. I believe this is a
Blue-headed Vireo. |

I don't believe the
contrast / demarcation between the auriculars and throat or the head/ nape
and mantle are great enough to rule out a bright Cassin's Vireo. Also the
mantle color and tertial edging appear better for Cassin's Vireo.
Both species of vireos molt on the breeding grounds so both are at their
brightest during fall migration. |
2nd round: |
18 Dec 2014 |

I think this is a
bright Cassin's Vireo and lacks necessary diagnostic field marks for a
Blue-headed Vireo (contrast between back and nape, contrast between

Blue-headed Vireo should be in fresh (and brightest) plumage. |

Seems like there is a quite distinct demarcation between the white throat
and blue-gray cheeks. Green back seems to contrast rather distinctly with
the gray head (especially visible in photo C). This isn't the most
clear-cut of examples, but I agree with the observer that this bird seems
more consistent with Blue-headed than Cassin's. |

After considering
other s remarks, I still see a bird with a blue-gray head contrasting with
a greenish back (especially photo C), relatively distinct demarcation
between the white throat and the blue-gray hood (photo D), and lores that
do not stand out obviously in contrast to the hood color (photo C), all
fitting Blue-headed Vireo and not Cassin s Vireo. |

I realize the main
point of discussion is the brightness and extent of demarcation of the
head coloration. To me if I were to describe the head color it wouldn't be
a light gray with little contrast to its surrounding neck and upper parts.
It would be a darker bluish/gray coloration and a much more line of
demarcation. The darker loral line of Cassin's is extremely variable and
is commonly found on Blue-headed. I would refer to the many photos of the
two vireos on the net. |

This is certainly a difficult one. There is overlap in a female B H and a
Bright Cassin's. To ID a B H out of it's normal range I like to be able to
see some contrast from the nape and the green back. The rest of the field
marks can go either way on a difficult bird like this one. The photo C1
does to me seem to show enough contrast that I would call this a B H |

I genuinely believe there is no distinct cutoff between field marks of the
3 varieties of Solitary vireo. One form flows into another in an unbroken
cline. I assume the genetics must be clearer for the AOU to have accepted
this split, but we are not, unfortunately, presented with a genetic
sample. This individual is certainly bright, and initially I was going to
vote for it despite it not being as bright as others I have seen
(female?). I came across a purported field mark that differentiates a
bright Cassins from a BH, and it is found in the article below (note

The written
description is pretty convincing on its own, and it seems we d
(ironically) probably not be debating the identification if there were no
photos attached to the record. So why do the photos seem so contradictory?
I believe most of this comes down to a misidentification of the age of
this bird, by both the original finder and the submitters of the report:
it was reported as an adult, but I believe it is actually a first-winter
bird. This explains both the relatively streaked back (not as streaked as
Red-necked Phalarope, but significantly more streaked than most
illustrations of non-breeding Red Phalaropes, where adults are usually
illustrated), and the black-based bill. As with the back, most field
guides illustrate adults in winter (neither my western Nat Geo nor my
Sibley show a first-winter bird), and adults have pale-based bills, but
first-winter birds can have solidly black bills, especially this early in
the season. My only hesitation with th!
is record is how thin the bill appears in photo B, but in both photos A
and C it appears typical of Red Phalarope and too thick for Red-necked.
Even in photo B, I d describe it as intermediate, or in the range of
overlap, for the two species. This change of apparent shape between photos
is in itself a good field mark for Red Phalarope: In addition to a usually
THICKER bill, the bill of a Red Phalarope is also much FLATTER than that
of Red-necked. I believe the bill s apparent thickness differs in these
photos precisely because of its flat shape, where more top and front views
like in photo A make the bill appear wider, and more strictly lateral
views like in B make it look thinner. In comparing photos B and C, note
how much of the top of the head we can see: the head is tilted ear-down
towards us in photo C, again emphasizing the broader flat shape of the top
of the bill, where it is tilted up in a more level view in B, showing the
relatively narrow side view. I am sti!
ll convinced this is a (first-winter, not adult) Red Phalarope. |

The photo is more ambiguous than the description might suggest. In the
photos, it almost looks like there might be white stripes on the
back/mantle. And the bills on some of the Red phalaropes I've seen have
been thicker than the one in the photo appears to be. But, since it is
hard to be sure from this photo, I'll have to go with the written
description.
(21 Oct 2014 - No, ID) Boy, this bird is very intermediate in its field
marks. I find the photos and write-up to be a bit incongruous. It's bill
is well within Red-necked range, and certainly not as thick as most of the
Red phalaropes I have seen, nor what I would describe as "very thick." The
head pattern (extent of white on forecrown and shape/extent of black
eyepatch) is a bit better for a RN than Red, but could be either. The back
mottling/flank streaking is intermediate too. However, the description of
this bird as bigger than the other Red-necks around it is a good field
mark, and I may rely on that in the end. For now, I am going to vote NO to
bump it into the second round. |

primary extension. How many primary tips, for example? Can we be certain
the bird wasn't missing an outer primary feather? (A juvenile wouldn't be
expected to be in flight feather molt, but a feather can always be
damaged.) Even if we take the observer's word that the primary projection
was short, what about this record eliminates (admittedly even less likely)
European Golden-Plover? |
