At least one of
these birds was still present as of August 01, 2007. Unfortunately there
has not been any evidence of successful nesting in the Kolob / Lava Point
area, although I'd be surprised if they haven't tried the last few years. |

Superb photos. I agree those must be two separate individuals based on the
different primaries and rectrices. This species has been seen in the Kolob
Terraces/Lava Point area of Zion NP several times in the past (Jun & Jul &
Aug 2004, Jul 2005, Aug 2006). It sounds like they are, at least
temporarily, seasonally resident there, as well as in the Pine Park area
further to the west. |

I'm leaning
towards this being a natural vagrant, given the timing and location.
Although there is obviously evidence of worn
feathers (on the breast and clearly on the tail feathers), I think this
fits timing of molt into definitive basic plumage (starting mid to late
July on body feathers and early August on flight feathers). |

After studying this
record, many photos and the literature extensively, I thought a good case
could be made for either
circumstance:
Wild and naturally occurring: Straying to Utah for the annual molt
migration is not out of the question considering the number of northerly
states and provinces where the bunting has been recorded. Recent
weather pattern might have influenced more northerly occurrence.
Ragged and worn feathers due to age of alternate plumage. Bright
colors instead of washed out. General wariness.
Captive escapee: Presumed excessive wear of flight feathers for a male of
a species that doesn t participate in nesting. Odd pattern of
missing feathers (nape, greater coverts, tertials, flank) that doesn t
conform to normal molt sequence for this species. Odd timing for
this appearance. Same underlying issue as with the last male Painted
Bunting record Utah has a high immigrant population from a country where
this species is a popular cage bird.
We ll never know the bird s origins for sure, however, I felt there were
clues in the condition of the bird s feathers and sought an expert's
opinion. I contacted Dr. Christopher W. Thompson, co-author of Cornell's
Birds of North America Painted Bunting species account and an expert on
Painted Buntings and molt. I asked him to review Paul Higgins photos. Not
only was Dr. Thompson enthusiastic and gracious toward my request, but he
also requested I send him high resolution photo files so he could review
the condition of the bird s feathers closely. Dr. Thompson's best guess
was that the bird was most likely wild and arrived in Utah under his own
power. Here, unedited, is his assessment in two messages:

he was so accommodating. Once again, if any committee member has

Clearly a male
painted bunting. The issue is whether this is a wild bird or escape. The
frayed tail is consistant with a caged
bird, but the lack of damage to the primary feathers suggests a wild bird.
I will go with the latter. |

I guess I'll cast
the only negative vote in order to give this bird some discussion - and
not just because I'm probably the only
Utah birder who didn't see it (the curse of being a full-time professional
birder - more than 200 species in Utah in August, not one new bird for my
state list). I wish this bird had been a female. Being a male, the issue
of whether or not it could be an escapee must be raised. The remote
location and the timing argue for natural occurrence. However, I'm
troubled by the pattern of wear in the tail, especially as compared to the
lack of wear in other parts of the plumage. My first reaction to the first
photos posted was "that bird's been in a cage." The tail-wear was exactly
what one sees with songbirds in cages, especially cages that are too
small. The later photos show a less clear picture of this, so maybe it's
just a matter of camera-angle (or the bird had more "free" time for
preening). I also find the bill-shape odd in a few photos, again in a way
that suggests captivity, but this could be just because of molting
feathers in the face. Anyway, I'll throw this to a second round just to
see your comments. Tell me why this isn't an escapee. Like I said, I wish
it was a female. |

I really don't like
the way this bird looks. The color in areas like the flanks and the feet
also look odd to me. But I guess for
a one year old bird coming into adult plumage it may be ok. I could go
either way on this one. |

This is a beautiful bird that I saw yesterday. There is no doubt in my
mind that this is a Paibnted bunting, and a skittish one
at that. As to whether it is an escaped bird, it must be noted that Fish
Springs NWR is very far from any significant human setlement. I do not
know the significance of the worn tail feathers as it touches on this
question (and will leave that concern to others), but the Cornell site
lists the (adult) molts as follows: flight feathers from mid-Aug to
mid-Oct; body feathers from early August to mid-Oct. I'm no expert in
molts, but it seems that this adult male would naturally be at the end of
its pre-molt period with the flight feathers being as worn as they would
ever get (i.e. just prior to being replaced). Also, the migration
period for this species is listed as starting in the last third of July
and extending through mid October, so this sighting is consistent with a
bird in tune with its natural migration urges. |

Ron has raised some very good points about this tanager. As Ron pointed
out, the bird in the photo certainly does appear to have a large bill,
yellow tail, and slight crest giving it the appearance of a large head;
all of these characters look better for a Summer Tanager. Also both
observers describe the wings as 'brown' rather than dark gray or black,
and the wing contrast in the photo is not outside the range for a Summer
Tanager. The timing is very peculiar for a female Scarlet Tanager as well.
I've listened to the audio clip many times, and I can't make a definitive
Scarlet Tanager call and what I believe I can hear, doesn't sound outside
the range of the Summer Tanager. |

Ron, thanks for providing your notes on the photos.
The physical evidence that accompanies this record is both helpful and
hurtful. The photos clearly show proportions, general colors and strong
contrast between body and wings; enlarging them causes pixilation and loss
of detail and may negate their utility. The YouTube recording seems to
document a single harsh call note given many times; both the Western and
Summer Tanager's multiple notes are different than that recorded.
Comparing the recording (computer speaker pressed to my ear) with multiple
files from the Macaulay Library of Natural Sounds convinced me that Colby
captured a calling Scarlet Tanager. LNS catalog #107334 documents a female
Scarlet Tanager that sounds very much like Colby's recording, minus the
background noise.
Matt's experience with the species and Colby's careful and lengthy
observation compensate for the image and recording quality and I believe
both observers saw, and Colby heard, a Scarlet Tanager.
Thanks to Colby for his valiant efforts to provide physical evidence with
this record. |

Physical evidence to
accompany a rare bird record is usually a birder's Holy Grail, but I
believe the photos and sound recordings have backfired on this one. We've
been led toward both Scarlet and Summer Tanagers and perhaps each of us
has been able to justify our opinions by squinting our eyes and straining
our ears. Several comments struck a chord with me: Terry's second and
third round comments on the photographs and Eric's second round comments
after talking to the observers: "(I know their view of the bird was better
than what we have in that photo)"
When I discount the images and recording, I believe the written word
picture documents a Scarlet Tanager by observers familiar with the sight
and sound of this species. |

I'm on the ropes regarding this record, and I do feel it could go either
way...but I just changed my mind again, and I'm about to give it a thumbs
DOWN. With all the flip flopping regarding this record, you'd think we are
politicians...haha...but I do think this says something important about
the record. And being the last person to review this record, and knowing
my vote will determine the outcome (and while admittedly I'd like to
accept it based off my own experience), I believe there are just too many
holes in the write-up, photos provided, etc. to definitively say this bird
was a Scarlet Tanager based on the record provided (not my own experience
with the bird).
I think the lack of any description of the call was a substantial mistake
by the observer. In addition, another photo or two should have been
submitted by the observer...and more attention to detail was needed in the
write up at the time of the observation by both observers. However, with
all of this uncertainty and holes...I still believe the recording (despite
the poor quality) point towards this record being a Scarlet Tanager...even
with the static in the video, the 'chick' portion of the Scarlet Tanager's
'chick-breee' call can be heard (albeit not well)...a side note for the
record, the 'breee' portion of the call was never heard in real life so it
was not the fault of the camera not picking it up. Nonetheless, I have
never heard a Summer Tanager
give this 'chick' call nor have I found a recording of a Summer Tanager
giving a call remotely close to the 'chick' call heard in the video (and
real life). And while I want to accept the record on this alone, I won't
because I!
don't feel I have spent enough time in the breeding range of Summer
Tanagers as I need to have in order to absolutely say Summer Tanagers
don't give some unrecorded 'chick' call...even though they don't in my
experience. |

I am on the fence and can easily change my mind. I have taken my share of
poor photos and can tell you a bird can look very odd in a bad photo. Just
looking at these photos I wouldn't be confident enough to call it either
species but I agree that there are enough blurs in just the right places
to make scarlet tanager questionable. The plump look of the bird in the
photo suggests it is fluffing out its contour feathers, could this cause a
scarlet tanager to look slightly crested?

I have had a chance to speak with Matt on a field trip. He has Lots of
experience with Scarlet Tanagers and felt the bird didn't look any
different than what he would expect a Scarlet to look like. I also spoke
with Steve and Cindy Sommerfeld on a field trip. They also saw the bird
and Steve feels very certain the birds bill was not large enough to be a
Summer. And I know Colby is a very observant birder. Plus there were
others that saw the bird.
I feel enough competent birders saw this bird and are confident it was a
Scarlet that I'm going to vote to accept. (I know their view of the bird
was better than what we have in that photo.)
I don't like the photo. The bird's body is plump and round unlike a
tanagers 'natural' shape. |

First of all I want to thank Ron for making us take a better look at this
record. I for one didn't spend much time looking at it
the first time.
Photo B does look like it could be a Scarlet Tanager but your not seeing
much except the green back and darker wings without wingbars.
Summers are typically more mustard colored but some are very green above
and yellow below and can have contrasting darker wings.
Photo A looks like a Summer Tanager. Even with the poor photo you can see
the more of the important field marks to separate the two. The bill does
look to large to be a Scarlet and the color of the underside of the tail (
yellow not gray like a Scarlet ) can be the best way to tell them apart.
And I can clearly see that in the photo.
I think this is a Summer Tanager. |

I am voting to "accept" in an effort to force this bird into the 3rd round
(yes, yes, you're welcome). The rest of you have
pointed out some very important facts, from which I have learned and for
which I am grateful. I think there are plenty of good arguments for voting
either way, though that fact alone may push me to vote against in the end.
It may be that this is one of those cases where we cannot be certain
either way.
Here are some thoughts gleaned from my review of various sources:
1) BODY COLOR: Back/body color is given by just about every source as an
important field mark. Scarlet tanager should have a greenish-yellow tone,
while the Summer should be more orangey-yellow. Both observers noted this
bird to be greenish-yellow in tone. The photos are poor and strike me as
inconclusive, though perhaps more greenish than yellowish.
2) BILL SIZE: Summer tanagers have larger bills. The 1st poor photo seems
to show a relatively large bill, though not conclusively so. However, if
you go to Cornell's "Birds of North America Online" site you will see
photos of Scarlet tanagers showing a surprising range of bill sizes. It is
my opinion that, so far as the poor photo shows, the bill of the bird we
are reviewing easily falls into the range of Scarlet tanager. [I will send
Milt/Dennis several photos from
this site for you all to compare for yourselves, and hopefully he will
make them available to you all for consideration. Note especially the
molting male Scarlet tanager's
large bill.] So bill size on this bird strikes me as inconclusive.
Colby, who is no slacker birder, specifically said the bill size on this
bird was too small for a Summer tanager.
3) SHAPE OF HEAD: Ron is correct in "pointing" out that this bird appears
to have a slight crest, which would be a much better field mark for a
Summer tanager. It makes the bird "jizz" like a Summer tanager to me.
However, birds often temporarily raise a "crest" when alarmed, as a bird
stalked by a birder might well be. Also the photo is rather fuzzy with
regards to that field mark, so I am not sure how dependable it is. Neither
observer noted a crested head (but neither did they note a round
head--which is less telling to me because a round head is the "default"
field mark and thus less notable).
4) CALL: Now, I listened to the YouTube video several times before I was
even convinced the periodic noise on it was supposed to be the "call". I
then compared it to the calls of a whole lot of recordings (especially on
the fabulous Xeno-Canto website) and found no instance of a Summer tanager
matching the YouTube noise. There was a closer match to
the Scarlet tanager. Based on my audio search, I would definitely lean
toward Scarlet tanager. The Cornell site states that the Summer tanager
always gives a >2 or 2-note click call (plus some other one-note whiny
calls), while the 2-note call of the Scarlet is highly variable (with the
first note being distinctly differently pitched than the 2nd, making me
wonder if the poor microphone on the videocorder might not have only
picked up one portion of the call). Rick, who hears Summer tanagers
infinitely more often than I do in his regular life, feels the call is
within the range of Summer tanager, and that is certainly significant. I
have personally never noticed a single-note call, but then I don't spend
enough time in SW Utah to be an expert. I would love to know what Mark
thinks about this issue, as he hears both species calling regularly on his
wanderings in Mexico. It is very unfortunate that Colby did not at least
attempt a description of the call, at least with regards to how many parts
each one had. Still, I think the call would have to be a field mark that
goes (perhaps inconclusively) onto the Scarlet tanager side of the ledger.
5) UNDERTAIL COLOR: I did not run into a statement in the field guides
that the UNDERtail color was significant, but the photos I've seen sure
seem to point to a yellow wash near the base of the tail being more common
in the Summer tanager. [I am also sending a
photo of a Summer tanager from
the Cornell site as an example of this.] Again, though, the photos are
not very clear on this field mark either.
I am not convinced any of the other field marks (lores, wing color, size,
etc.) are conclusive. |
3rd round

6 Apr 2008 |
No, ID |
As I discussed above, I believe the predominance of field marks points
vaguely toward Scarlet tanager. But I do not think the bird is a Scarlet
tanager beyond reasonable doubt, based on the submitted record. And that
is the better standard rather than "most likely species". |

I'm hoping this
record will stimulate some discussion. |
2nd round |
1 Oct 2007 |
Acc |
Obviously this bird cannot be distinguished further than western
flycatcher.
I submitted this record for two reasons. The first is that as far as I
know, there are no other reports of western flycatcher or any other
Empidonax flycatcher in the winter in Utah.
Secondly, I believe that it is an oversight that Pacific-slope Flycatcher
is not currently on the Utah list.
Even in hand, very few of these flycatchers are distinguishable, with
nearly all measurements showing extensive overlap. The only reliable way
to distinguish these species is genetic analysis (and allozyme analysis
shows these are distinct species that have been separated for eons, have
very limited genetic relationships, lack evidence of hybridization, and
show assortative mating in areas of overlapping breeding habitat). In
addition, there is strong evidence that the Channel Island Flycatcher
(currently recognized by the AOU as a subspecies of Pac-slope, E. d.
insulicola) is likely a separate species. Mitochondrial DNA analysis is
going to provide insight into speciation and genetic relationships of many
currently recognized subspecies over the next several years. And will very
likely result in many, many additional splits that will be nearly as
difficult as western flycatchers (e.g. Red Crossbills, Spotted Towhees,
Common Ravens, Song Sparrows, Savannah Sparrows, Fox Sparrows, Bushtits
..and many more).
I believe we should consider a process to evaluate these splits and their
corresponding probability of occurrence in Utah as they are accepted by
the AOU. As I stated above, I believe it is an oversight that the
Pacific-slope Flycatcher is not on the Utah list. I m completely convinced
it is a regular migrant through southwest Utah. Nearly all western
flycatchers that I ve observed in lowland locations, that have also
vocalized, have given both songs and calls consistent with Pacific-slope
Flycatchers (including the male s two-note tseeweep contact call). Also
other factors previously discussed (including, timing, habitat, lowland
occurrence) suggest these are Pac-slopes rather than Cordilleran
Flycatchers. In addition, several other species sharing the Pacific-slope
s breeding range and migration patterns are regular or somewhat rare
migrants through the southwest corner of the state (e.g. Cassin s Vireo,
Townsend s Warbler, Hermit Warbler, Red-breasted Sapsucker, Vaux s
Swift). So there is no reason to expect this species does not regularly
move through southwest Utah.
With all that said, we face a bit of a quandary, and it s likely to get
much worse over the next several years. How do we empirically show a
species occurs in the state, if we cannot visually or audibly recognize
it? In the case of Pacific-slope Flycatchers, there is no reason to
suggest it doesn t occur, and in fact it is highly likely that it is a
regular migrant through the southwest corner of Utah. However, it is
visibly indistinguishable from Cordilleran, shows overlap in songs and
vocalizations, and even mist-netting and measurements are unlikely to be
definitive. So the only empirical solution is genetic analysis, which is
also prohibitive for a non-descript uncommon to rare migrant through the
state (yet rangewide a rather common species). I d be very surprised if
anyone has ever done genetic analysis of Pacific-slope Flycatchers in say
Nevada, however, it is currently on the Nevada checklist and was added
following the official split of Western Flycatchers, based on the high
probability of occurrence and migration patterns of sympatric breeding
species.
So, I d be interested in hearing what you all think about a process to
deal with future splits of current subspecies. I believe this is really
just the beginning of a complex problem. |

I also believe the
Pacific-slope Flycatcher occurs in Utah, but I don t think we can add the
species to the state checklist on the basis of this record. The only
information that infers the bird was a Pacific-slope is that the habitat
was consistent with habitat from confirmed winter records in other states.
Conventional wisdom counsels that the Pacific-slope and the Cordilleran
can t be separated in the field unless the bird is a calling male, and
even that is somewhat uncertain. This may not be a species that allows us
to accept a record with a conventional sighting and documentation, even
with excellent photos or
audible evidence. Perhaps it will take convincing banding measurements on
a future record and that seems unlikely. On another note, I m confident
that the record documents a Western Flycatcher and not a Yellow-bellied. |

This species doesn't belong on the checklist according to our current
standards and therefore, earns my "Not accept" vote again. Know that I
believe the bird occurs in our state and that I think I saw and heard a
Pac-slope Flycatcher in Southern Cache County in June 2004. However, our
checklist doesn't have a category for birds that can't be identified by
conventional means presently available to birders and banders. Adding a
hypothetical category as Rick and Ron have suggested is likely the
solution, but it also could open Pandora's Box if we don't carefully
define what situations fit the category. I don't want our checklist to
become subject to the concept known as observer expectancy bias ("I
wouldn't have seen it if I hadn't believed it!") in the scientific world,
or wishful thinking in layman's terms. I'll continue to vote
conservatively on this issue. |

I appreciate the
thorough description and review of records. However, as Rick points out,
this species is not distinguishable in the field without a song (even then
it can be difficult). While this may have been a Pacific-slope Flycatcher,
I cannot accept it only based on past winter records. I do appreciate the
submission of this record as in the future, we may have more information
on how to distinquish this species in the field and the photos might be
sufficient. |

I am still not
convinced the Pacific-Slope and Cordillerean are two distinct species of
the Western Flycatcher. However, since they are recognized as separate
species by AOU I believe the observer has done excellent research and
review on determining that the bird seen is Pacific-slope given where they
migrate and winter and what has been identified in past winters in the
Southwestern U.S. |
2nd round |
4 Oct 2007 |
Acc |
As long as AOU is recognizing Pacific- slope Flycatcher as a distinct
species I agree with Steve that it is an oversight that
Pacific-slope Flycatcher is not currently on the Utah list. The factors of
timing, habitat, and lowland occurrence all strongly suggest to me that
the bird seen was a Pac-slope. I think when empirical data is not possible
we should consider other data in our evaluation of records.
Juvenile Sapsuckers in late fall and winter are identified quite often by
presence or absence of juvenal plumage since juvenal plummage in
Yellow-bellied Sapsuckers is retained into late winter while Red-naped
develop adult features by late september. Could we not identify the
Western Flycatchers by what we know of timing, habitat, and lowland
occurrance? |
Mark S. |
26 Aug 2007 |
No, ID |
This is a really
tough vote for me. I agree with everything in Rick's analysis. In as much
as there are really two species here (I'm personally skeptical of the
split), I believe that the Pacific-slope form must occur in Utah during
migration, probably regularly, and especially likely in the SW desert,
just as Rick says. "Western" Flycatchers are common throughout Mexico in
winter, and the conventional wisdom is that the high-elevation birds are
Cordilleran and the low elevation birds are Pacific-slope, but in most
cases there's no way to test this theory. I've been noting the calls
everytime I hear them call, and so far all of the calls I've heard are
consistant with this idea (realizing that even vocalization isn't always
reliable). Presumably in-hand measurements are the only reliable way to
identify these "species" away from the breeding grounds. Although birds
have been "positively" identified as Pacific-slope in neighboring states
during migration, and logic says that this should be a Pacific-slope (and,
in fact, I believe it is), the fact remains that we can't say so with any
certainty. The only
reason this is presumably a Pacific-slope is the location and time of
year, something that isn't very dependable outside of the breeding season.
Vocalization would add to the confidence of this identification, but to be
certain we should have specimens/measurements to establish occurrence of
this "species" in Utah. Perhaps with more hard data (but who will collect
this?) on where and when these occur in Utah we can get a better feel for
how reliable it would be to say "fall/winter 'Western' Flycatchers in
riparian zones of southern Utah are most likely Pacific-slope." I don't
think we have enough information to make that conclussion
right now - even though I think it's the correct one. |

Great Discussion and a very interesting dilemma. This bird is out of
place/season. Is this a farther-out-of-place more-common bird, or a
less-common bird less-out-of-place? I don't think elevation and season are
enough to identify this bird without real convincing data about the winter
records of the two species. If we were to accept this record it would
become documentation of a winter occurrence of Pacific-slope Flycatcher.
Documentation that others may use to make future hypotheses. We shouldn't
do that without knowing it is Pacific-slope. |

I do agree that pac-slopes
do come through in migration and probably aren't that rare.But without
having the bird in hand you can't label it a pac-slope just because it may
be more likely.Most expert birders that I know if they see a Western
Flycatcher in winter they call it just that a Western Flycatcher. I for
one don't think they should even be split. There is just to much overlap
in their calls. |

I do not argue with anything that the observer noted. I think it is very
likely indeed that this species passes often through the
SW corner of our state. But, as the observer notes, the two members of the
"Western Flycatcher" complex are essentially indistinguishable in the
field when not singing (and even in that there is some overlap). I am not
sure that there has been sufficient study of overwintering birds to be
statistically certain that this was a Pacific flycatcher. I would urge
Rick to continue his observations of this complex and perhaps see if he
can get some of his colleagues at DNR to mistnet some of
those lowland migrants and overwintering individuals for more definitive
data. I agree we should be able to add that species to our list with a
little more scientific effort. |

I suppose we could always pull out the "it may be a hybrid" card. However,
none of the characters we observed gave any indication that it may have
been a hybrid. And while we did not observe a portion of the perched bird,
none of the characters we missed are diagnostic or as distinctive as the
face, head, and nape pattern. However, I suppose as the saying goes, "If
it walks like a duck, and talks like a duck, it may still be a hybrid". |

A detailed written
account of a well-seen distinctive species would be a reasonable
substitute for physical evidence to accompany a first-state record.
Unfortunately, the bird only allowed a partial view and the Gilded Flicker
is not distinctive enough from an intergrade red- x yellow-shafted or the
less common Gilded x red-shafted flicker. A hybrid needs to be eliminated
from consideration. Researchers identified a flicker in Beaver Dam Wash in
Washington County in 1964 as a
Gilded and noted the bird was a first-state record (Behle, 1976, referring
to Aud. Field Notes 18:377, 1964); Behle also noted another Beaver Dam
Wash record in Arizona (Aud. Field Notes 20:591, 1966) where a researcher
identified two flickers that were collected as Gilded x red-shafted
hybrids. I think both pure Gildeds and hybrids are possible and
therefore, the record must leave no doubt. |
2nd round |
9 Dec 2007 |
No, ID |
Our bylaws provide us with guidance for voting on a first state record,
and this one doesn't meet our criteria. To save everyone the additional
burden of researching the germane paragraph, here it is:
11. First State Records. It is preferable that a first state record have
some form of physical documentation. Acceptable evidence could consist of
photographs, sound recordings, specimens, verified band numbers, etc.
However, a first state record may be accepted without physical
documentation with these considerations in mind:
(1) The species is obvious and easy to identify and cannot be confused
with a similar species.
(2) The observer is familiar with the species.
(3) The observer is known by the committee members as a careful competent
observer with experience in documenting rare birds.
(4) There are multiple competent observers that submit separate, careful
documentation.
Only items 2 and 3 apply to this record. I'm unwilling either to dispense
with our bylaws or to accept a first state record of a partial view of a
species that hybridizes with others, and no physical evidence.
Sorry to flog you all with the rules; it's annoying, I know. But if it's
OK to ignore our own criteria on this particular record, in what other
circumstances may I dispense with our bylaws? |

When I reviewed and voted on this record in the first round, I voted based
on the merits of the record without being cognizant of our first-state
criteria. I still hold the opinion that the partial view of the bird
didn't provide enough information to prove the ID when pure Gildeds and
hybrids are possible in the southwest corner of the state. In addition, I
didn't find any additional or compelling information in the other comments
either to change my mind or to make me dig for more references, and I dug
a lot the first time around. |

This is a tough
record to assess. The viewer's comment that the bird "appeared to have
yellow shafts on wing feathers" is not real convincing. Or could it have
been somewhat yellow-orangish, indicative of a hybrid? The most definitive
mark was the brown on the crown and nape, but red-shafted (northern) has
brown on the crown, extending sometimes beyond the eye. The lack of a view
of the tail, back and barring on the lower belly make the evaluation a bit
difficult. I would like
further discussion of this bird. |

This is a significant record whether it's a Taverner's/ Richardson's
Cackling Goose or a lesser Canada Goose, as none of these subspecies
should be anywhere near Fish Springs in the summer. There is not a lot to
go on, other than the observed small size and steep forehead/small bill
(which both suggest cackling). I'm going to vote to accept this one and
see if we can get some discussion going on the characteristics to
distinguish these tricky subspecies. |

I believe the description is adequate. Although the date is unusual,
perhaps it's not unprecedented for a first summer goose. I've not any
experience with a summering Cackling Goose, however there have been
several young geese that have remained to spend their first summer in the
St. George heat, including a Greater White-fronted Goose, a Snow Goose,
and two Ross's Geese since 2002. |

The lack of
well-developed ID information available to distinguish between B.h.
hutchinsii, B.c.parvipes, and even B.c.taverneri undermines this carefully
written record. Size overlap between the three subspecies/species makes
the perception of the review bird s size less relevant and although the
description of the bill as stubby is helpful, comparison of the shape of
the forehead to that of the other geese present, likely B.c.moffitti, is
less so. It seems a no-win situation. I
regret having to vote not to accept this record; my vote is not at all a
reflection on the observer. I think Cackling Goose records with the best
chance of acceptance will be the more distinctive subspecies. |
2nd round |
28 Jul 2008 |
No, ID |
My second round of study on this record brings up this question: Why is
this bird not a B. c. parvipes? Answer: I don't know. A complete
description of the structural elements of the head would have been
helpful. Bill size of B. h. hutchinsii approaches parvipes in many birds
and overlaps in male B. h. hutchinsii and female B. c. parvipes. I don't
think the difference is discernable in the field. The observer said the
review bird's bill was half the length of surrounding moffitti bills, but
the literature shows moffitti's culmen length is only about 20 percent
longer than hutchinsii's, leaving me with questions. Body size between
hutchinsii and parvipes overlaps completely--3-7 pounds for hutchinsii and
5-6 pounds for parvipes. Color of both parvipes and hutchinsii breasts is
similar to that of moffitti, therefore, breast color in this record is not
a useful measure. Upperparts color including feather edging would have
been a more useful measure. With the above considerations in mind, I don't
think the observer adequately elimanted the Lesser Canada Goose, B. c.
parvipes. |

Not sure which way to go given the date, but as others have brought up it

I have long struggled with this record, and could have gone either way on

The timing of the record is very unusual, as all subspecies of Cacklers
should be far to the north at that time of year (breeding season). On the
other hand, any subspecies of the Canada goose that small should also be
far to the north. So the timing is a wash. |

However, the photos are the most convincing evidence of a Blue-headed

I think this record is marginal, and I could go either way. The timing of
this record is marginal, as Tennessee
Warblers are not typically moving south of their breeding areas until late
August / early September. However, I suppose the "un-streaked

eliminate an Orange-crowned Warbler. The rest of the description could

Regardless of the references noting that the pale mark at the bend of the

saw (record 2005-27) convinced me that Tennessees can have that pale mark.
I did not see or report the white mark on "my" Tennessee, but Jack told me
later that he saw the mark on the bird a couple days later. His comment
surprised me because I felt like I had observed the bird thoroughly and
hadn't seen it. His noting the mark was unsolicited, as well. Is it
possible this mark
is present on some birds, but not visible all the time? Another field

Ron Ryel researched and found a photo of a Tennessee with a white wing

barring and described flight behavior. |

I agree with Terry's comments about the lack of detail in this record.
This is the most frustrating record of the year, especially because a
critical detail like the position of the white band within the tail must
have been visible, but the observer failed to mention it. Still, I
distilled enough information from multiple reviews to convince me that the
observer really did see a Zone-tailed Hawk. Those features included size
smaller than a TV, sailing with a TV, rocking flight pattern,
black/grayish black color, and barring on flight feathers. |

Generally a good
description, especially the wing and tail patterns and the flight pattern
(rocking TV-like). The flight pattern
and light area in front of the eye should eliminate a dark broad-winged
hawk. |

My comments from the first round still apply. I feel other species are
safely eliminated, despite the lack of some details. |

I don't feel
comfortable accepting this record on the first round. I believe there is
critical information lacking such as
description of the bare parts(i.e. cere, beak, legs) |

I Change my vote on this one to accept based on other committee members'

Excellent
description and analysis of similar species - noting similarities with
Turkey Vultures also present helps. |

The barring on the flight feathers was a nice detail. |
