Looks good for a juvenile Yellow-bellied Sapsucker. Any sapsucker in
December with this much juvenile plumage will be a Yellow-bellied. The
paler plumage and streaked crown is also good for Yellow-bellied vs
Red-naped. |

The over-all
brownish cast, the appearance of a brownish lightly streaked crown, and
larger unstreaked creamy white/yellowish central breast area are all
consistent with an immature YBSA. The late retention (Dec.) of the
juvenile plumage is also characteristic of a YBSA. |

Bird looks good for adult male Brown-capped Rosy-finch. Has a a cold brown
coloration vs warm brown of a GCRF. Has a mostly black crown with a
minimum of gray that no adult male GCRF would show. Looks like a different
adult than the one submitted by Ryan O'Donnell because of different
amounts of black and gray on the crown and differing amounts of pink on
the underparts.
Additionally, Michael Hilchey (co-lead of the Sandia Rosy-Finch Banding
Project) weighed in on this bird and said: "Adult M BCRF. I don't think
this is the same as the first or 2nd photo."

After noting the comments of the other committee

The large size, overall greenish coloration, and
rosy(?) head cap, are all characters of MAHU. However, I'm not sure other
possible large immature hummers have been adequately addressed, and
there's no mention of any throat coloration, presence of facial markings,
and tail characteristics. The nine month lapse since the observation,
which was from memory, doesn't add to the "best placement" of the bird as
a Magnificent Hummingbird. |

Well, late to the party, but, hey, the music was
good . . .
I'm going to be a lot less tentative on this record and just say that I
don't think she saw a Baltimore Oriole at all. Like Larry, I think she saw
a Black-headed Grosbeak, and joined the legions of eastern birders who
made the mistake of calling a BHGR a BAOR. Clearly it's one of the most
common i.d. mistakes in Utah.
There is nothing in the description that eliminates BHGR, except, perhaps,
the orange wing stripe. But that could easily be confused for the orange
on the side of the neck, or even the wing lining peaking around at the
shoulder, especially in a naked-eye view. She makes no note of bill shape,
another obvious way to distinguish these two.
But there are several items in her description that strongly point to BHGR.
First is the habitat - oak scrub on a dry slope. It's perfect for BHGR,
but would be an odd place for even a vagrant BAOR. Even stranger would be
a vagrant BAOR singing from such a location, and singing continuously.
While vagrants in Spring do sing, they rarely sing repeatedly from
inappropriate habitat. However, the location and habitat are perfect for a
singing BHGR at that time of year.
Finally, her description of the song sounds more like BHGR than BAOR. Both
birds have similar-sounding songs, note-wise, but BAOR is much slower,
more languid, and less continuous than BHGR. Her description of "singing
on repeat" fits BHGR, and not BAOR. |

I'm not comfortable with the description on this

they make no attempt to eliminate western birds like a Black-headed

to see it go to a second round. |

This is one of those records where I don't really know how to vote. On
one hand, the description fits a Baltimore oriole. But it falls just
short of definitive because of a lack of detail. Is there any way to ask
the submitter to elaborate a bit more? Here are my issues:
1) The head was black, as it should be. But how far down did the black
extend? Was it just black on the crown and nape like a Bullocks? What of
the upper breast?
2) In one place, the observer described a white stripe on the wing, in
another an orange stripe. But nowhere are both described simultaneously.
Is that just incomplete description in any one place or is it a typo?
I think it very likely the observer saw a Baltimore oriole, but the
description leaves me a bit uneasy, considering how rare these birds are
in Utah. Are we allowed to call/write the observer to elicit more
details?
I'm willing to reconsider this in the second round, but I thought I'd
express some reservations and see if it is possible to tighten this record
up a bit. |

Even though there is a good possibility this
bird was a Mourning Warbler, several questions and problems are apparent.
First, the observer puts most of his emphasis on the lack of any eye-ring,
which is certainly a character of MOWA. However,an immature or female of
either MAWA, COWA or MOWA species varies in the extent or absence of an
eye-ring. Also, if it were a male, as recorded, there was no mention of a
black "veil" or throat patch. A one minute observation time is a little
troublesome, especially with other closely appearing species.
Since it would be a FOS record, and the committee has reviewed and denied
a couple of previous sight-only records, I feel this record falls in the
same category. |

The absence of eye-arcs described for this bird IS quite compelling. I

This is such a rare Warbler in the west
(especially in Spring) That I would like to see it go at least to a 2nd
round. The description of the bird not having eye arcs seems convincing
but this can be a difficult bird to see well. On the other hand a male in
spring if seen well should be pretty straight forward. The observer does
have experience with the species. |

I wish the observer had described the tail
length relative to undertail coverts, black pattern on the lower portion
of the breast bib, the color of the lores, and vocalizations. There is
some overlap between field marks between this species and the
MacGillivray's, but the overlap in the eye-arcs seems to go the other
direction only (i.e. some Mourning warblers have vague eye arcs, but all
adult male MacGillivray's warblers have eye arcs). At least, that is what
the books I have checked indicate. |

I have not heard anyone address my comment

MacGillivray's warbler males sometimes lack eye rings? I have heard the
converse, but not that. |

Even with a good thorough report and

Flycatchers" - Pacific-Slope and Cordilleran. There is too much overlap
not only on field identification characters, but also call notes and song.
I don't doubt that PSFY could occur in Utah but I'm not sure how we'll

This record shows a Western Flycatcher but I
cannot accept it as a Pacific-slope Flycatcher.
The ID rests solely on description of the call and its audio recording.
The sonogram however shows a poor image of the suggested upslurred
whistle, which I cannot hear on the recording nor clearly see in the
sonogram. The recording also shows a good image of one part of the PSFL
song used as playback (the Ptik!, according to the observer). Even if the
sonogram were of better quality however, I'm still not certain my opinion
would change given the ample warning of identifying migrant PSFL from
call-only. See BNA species account of Pacific-slope Flycatcher written by
Peter Lowther. I can upload a pdf of the pertinent page if anyone is
interested. |
2nd round: |
6 Sep 2015 |

As I've previously commented the description,
and especially the audio, does not definitively ID a Pacific-slope
Flycatcher.
I'm not discounting Rick and Steve's opinion that this species may be a
common migrant in SW Utah but I don't feel THIS individual record has the
quality to confirm a first-state record.
Is there literature that addresses the relative abundance of these two
Western Flycatchers during migration (spring AND fall) in adjacent Nevada
and Arizona? Any information that can be shared will be useful. |

Wow, you sure know how to welcome someone to the
committee . . .
O.K., this is probably the toughest question we have to face, which
perhaps just indicates how valid this split is in the first place.
I understand all of the arguments, and "theory" as to which should be
migrating where and when, and generally even live by a similar
distinction. Here in west Mexico, PSFL is our most common wintering empid
by far, so I hear and see these almost daily for much of the year. I'm
sure that I could walk out of the house right now and find one within 15
minutes.
But we also commonly have COFL, and the convention for distinguishing
which is which is strikingly familiar - those in the highlands are COFL,
and those in the lowlands are PSFL. I HATE doing i.d.'s on nothing more
than habitat. So for years now, I've been paying close attention to the
calls - even knowing that I've heard COFL (on territory in Big Cottonwood
Canyon in June) give PSFL call (and have recordings of the same), and have
heard from others that this can happen at various parts of the COFL range.
In spite of doubts as to how reliable the call is, I have yet to hear an
exception to the high/low rule here in Mexico. Every bird in the highlands
has given a COFL call, and every one in the lowlands has given a PSFL
call.
So, given that experience, the "conventional wisdom" from surrounding
states, and the local knowledge from birders on this committee, I was
predisposed to accept this record, especially given Kenny's excellent job
of documentation.
So why am I voting to "not accept?" Because, when I listened to the
recorded call, I heard a two-parted call more like COFL than like PSFL.
That is to say, that if I heard it without any of the associated
information, I would be likely to call it COFL. The sonograms didn't help
me get past that impression, either, since I find them inconclusive.
This may be a PSFL. But for a first-state record, I think we need a
cleaner example. |

This species is best separated on it's breeding
range. In migration I think they are best called Western Flycatchers. But
they are separated in other western states by the habitat that they are in
during migration. I've always thought that pac slopes come through the
desert S W of Utah and I have seen birds myself at Lytle that I assumed
were probably pac slopes but I just let them go as westerns. I'm not sure
they should have ever been separated.
This is another one that I would like to see in a 2nd round and see if I
can get some conniving comments from others even though I feel pretty good
about calling this a Pacific-slope. |

I am very reluctantly voting on this record.
It's honestly a bit hard for me to tell where the vocalizations of one
"species" of Western flycatcher end and those of the other begin. I have
agonized over quite a few Xeno-Canto recordings, and I still feel less
than sanguine about the distinction being clear-cut.
That being said, I do feel this individual does sound more like a
Pacific-slope than a Cordilleran. |

I know I am going to exasperate at least
two members of the Committee whose knowledge I highly respect, but I am
going to switch my vote to No. I really would like to switch my vote to "I
don't know", but there is no abstain option on the pull-down menu. This is
the species I feel least competent to vote upon as a migrant, and I wish I
could just acknowledge that by being allowed to abstain.
Here is my reasoning for switching (read waffling), based mostly on a link
provided by Jack (thank you, Jack):
1) The more i read about the various calls given during migration and
"bilingual" individuals, the less sure I am that anyone can be certain of
any one migrating individual's status unless they give a perfect,
notarized repertoire of songs/calls, accompanied by a DNA sample. This
individual sounds to me more like a Cordilleran (sorry, Mark, ole buddy),
but not in a definitive-leave-no-doubt fashion.
2) There is a large area of suspected sympatry to the north of us, well
illustrated in Cornell's map: http://bna.birds.cornell.edu/bna/species/556a/galleries/figures/western-fly--map/image_popup_view
I have run into several references over the years, referring to the need
for further study of birds in this overlap zone. This implies the
possibility of hybridization.
3) I know some argue that "science" says these two forms represent two
distinct species, but in the end this is a question of definition rather
than genetic drift. Whether the "Western flycatcher" represent one, two,
or three species seems to me a lot like asking whether Pluto is a real
planet. Depends which definition of species you subscribe to. Yes, I know
we defer to the experts at AOU to answer that question, and I am very
happy to do so, but it sounds like the species boundaries have not been
entirely resolved for all portions of this empid's range. Thus, I am
uncertain whether we fully understand from where a migrating individual
comes -- the coast, the deep interior, or the gray overlap zone to the
north of us.
I am sorry. I would prefer to abstain, admitting ignorance, but if I must
vote on a state first (yes, sorry, Rick, I know you feel this is NOT a
state first, and I believe you), I will now vote NO. I do so not because I
doubt that it likely is a Pacific-slope flycatcher, but because I am not
sure we can prove it without more evidence. [Where is Audubon and his
shotgun when you need him?]
Kenny, hell of a record! I suspect future generations will have an
opportunity to reexamine this with more understanding and re-evaluate your
excellent sound documentation with more certainty. |

Although the record is unusual for being
'optics-less' as the observer admits, the description is relatively

I still feel the observer did not adequately
rule out the more likely Swainson's hawk, which is a species resident in
that part of Utah. I find it interesting that the Swainson's hawk was not
considered by the observer in the Similar Species portion of the record
(perhaps because that species does not regularly occur in Minneapolis or
perhaps because the observer considered that species and thought it
nothing like the bird he saw). Of our regular buteos, Swainson's have
sleeker wings, proportionately thinner and longer than a Red-tail or
Ferruginous, thus better approximating a kite.
The observer says the bird was smaller than a Red-tail and larger than a
kestrel, but does not say that either species was present for direct size
comparison. In the absence of direct size comparison, that field mark is
less certain.
In my opinion, the description fits a Mississippi kite well (perhaps
best), but is close enough to fitting the more common (esp in July)
Swainson's that the burden of evidence falls short to vote to accept. |

Even with a detailed comparison of PSFL and COFL
recordings and sonograms I still am not totally convinced we are simply
looking at individual variations and not separate species. Also, has COFY
been recorded at Lytle Ranch during migration periods? We can't assume
those "Western Flycatchers" seen on the Beaver Dam Slope during migration
are PSFL and those in the upland areas COFL. |

I applaud Kenny for contributing this record for
review. This is a difficult identification requiring detailed analysis of
high quality sonograms. I simply have too many doubts still to accept this
record in the first round. Perhaps clarification on the points below
(especially #2) will convince me otherwise.
1. Can the observer provide the full recording or was only the single song
captured (2-3 seconds). At one point in the report the bird was observed
(heard) for 30 seconds, in another place for 15 seconds, and then 3
seconds are shown in the sonogram. Is there more of a sonogram to share?
2. I appreciated the representative sonograms for comparison to this
record. However I think you would agree that there is quite some variation
among the songs provided for PSFL at xeno-cantho. Can the observer provide
a more complete analysis of the sonogram. I'm attaching a
table published in
'Birds of North America Online' that lists quantifiable details of the

I'm still voting NO on this record for the
reasons I, and many others, have already expressed regarding the use of
calls and song for identification of migrant Pacific-slope Flycatchers.
My sense is to keep the species on the Utah review list but discontinue
voting, at least temporarily, on these records. I also worry that removing
PSFL from the review list will only diminish the amount information for
this species in Utah, the exact opposite of what is needed. |

O.K., the song is more convincing than the call
note, and this recording sounds like PSFL, and the sonograms are a better
match. I can live with this one for a first state record. |

I'm going to change my vote. I choose "Accept,
but not at species level." I suppose that this is effectively a "no" vote;
at least that's my intent.
I'm perfectly happy to accept it as a "Western Flycatcher," but have
doubts, as do many, that Cordilleran and Pacific-slope represent good
species. Specifically, recently released results of extensive, range-wide
DNA analysis of these species has revealed that the population of
Cordilleran Flycatchers has been heavily invaded by Pacific-slope genes
(but not vice-versa), to such an extent that virtually all of the
Cordilleran Flycatchers of Utah carry Pacific-slope genes. Apparently the
only populations of Cordilleran Flycatchers without Pacific-slope DNA are
in southern Colorado, Arizona and New Mexico. Given this new data, I
suggest that we table discussions of records from this complex, and return
to calling them "Western Flycatchers," until these taxonomic issues are
better sorted out.
Here's a link to a note about this study:
http://birding.aba.org/message.php?mesid=1027591&MLID=NY01&MLNM=New%20York
And here's a note from the primary author regarding these results:
"Because I am the primary author on the most recent genetic analysis of
these species
(mentioned in the post by Douglas Futuyma cited by Peter Post), I thought
that I could add a little to this discussion. I recently finished my
dissertation research, most of which focused on these two species. While
it is true that the two species are admixed in their DNA over a large part
of the West, the Pacific-slope populations west of the crest of the
Sierra, Cascades, and Coast Ranges (i.e., the Pacific Slope) remain
genetically and phenotypically distinct. We know that gene flow from
interior populations to the west slope Pacific-slope populations occurs to
some extent, but it does not result in widespread genetic mixing like it
does on the east slope.
So, it is a little more complicated than two species just merging (back)
into one. Pacific-slope seems to be merging more into Cordilleran than
Cordilleran is merging into Pacific-slope. I'm not sure taxonomists will
take this nuance into consideration when deciding what to do with these
species, but from an evolutionary perspective, it is interesting. I will
have at least a couple of more papers on this out soon.
As soon as you cross the crest of the Pacific Slope to the east side, you
encounter mostly genetically intermediate birds with intermediate songs or
calls. There is some proportion of admixed birds in populations all the
way to the Black Hills and to northern Utah and Colorado.
On the other hand, you almost never encounter birds with intermediate
songs or calls on the west side and almost no birds are mixed in their DNA
and these are limited to areas like Mt. Shasta in California, which is
very close to admixed populations.
So, if you have seen a Cordilleran Flycatcher in southern Colorado, New
Mexico, or Arizona, you are probably safe in terms of listing. If your
Cordilleran Flycatcher is from Alberta, Idaho, Montana, Wyoming, or the
eastern parts of the coastal states, you have a higher likelihood of
having seen an admixed bird.
One last thing in terms of identifying these species. I have not formally
analyzed the position notes yet (i.e., "pee-o-weet" and "weet-seet") but
it seems that these change in a slightly different way than the songs
geographically. I.e., you can encounter birds whose position note is more
purely Cordilleran that has a more intermediate song type and a more
intermediate genotype.
I hope this is interesting to some of you.

I have all the same problems with this record as
I do with 2015-18. Until someone comes up with a more reliable way to
separate Western Flycatchers in the field I don't see how we can call them
anything else but a Western.
As we have all said there's no doubt Pac slopes go through Utah but I

I do agree we shouldn't be reviewing this
species because as I said before that outside of their breeding range I
don't think we can call them anything but a western Flycatcher. There is
just to much overlap in calls and songs.
Then you could also throw in the hybrid word which there is talk about
too.
Maybe I'm being old school but I haven't seen convincing evidence To my
satisfaction to call a out of range bird anything but a Western Fly.

No, ID |
I voted in the affirmative on this record a few
day prior to my monumental waffling conversion to the NAY crowd on the
previous Pacific-slope flycatcher record (2015-18) because of the
uncertainty of differentiating "Western flycatchers" by call during
migration when bilingual populations occur to the north of us. So now I am
changing my vote NO on this one as well, to be consistent in my
conversion.
I think these are both very important and well-documented records which
will likely be re-evaluated in the future as a better understanding of the
species boundaries in the "Western flycatcher" complex becomes available.
I am gratified that Mark has come to my rescue with scientific citations
to support my discomfort as to the certainty of identifying members of
this complex to species in our part of the world.
Also, I agree with the philosophy, so well stated by others on the
Committee, that we should not vote to accept any one record simply because
the species commonly migrates through SW Utah, perhaps even predominantly
as regards this complex.
Mark may be wise in his suggestion that we "table discussions of records
from this complex, and return to calling them 'Western Flycatchers,' until
these taxonomic issues are better sorted out." |

The
spectrogram for this bird closely matches the other spectrograms for
Pacific-slope Flycatcher, especially the diagnostic 2nd element of the
song which greatly differs between Pacific-slope and Cordilleran.
Also I know last time when there was voting for this bird, there were
comments made about whether it is a "good" species or not or if it should
be lumped with Cordilleran back to Western Flycatcher. This committee
shouldn't have to worry ourselves with issues like this. According to both
the AOU and ABA, Pacific-slope Flycatcher is still a valid species. It is
up to us to determine whether this bird was a Pacific-slope.
We should leave the larger question of if this is a valid species to the
higher up committees and if there comes a day when the two species are
lumped back together, we can lump them too- just like just happened with
Thayer's and Iceland Gull. In the meanwhile, I think it is important to
properly document this species in this state and see what information we
can glean from its occurrence. |

1)
Flycatchers don't learn their songs and calls like other songbirds. They
are innate as the calls are hardcoded in their DNA. This rules out a
Pacific-slope learning the wrong call. More info can be found here:
http://earbirding.com/blog/archives/1956
2) The current research out there shows that Pacific-slope and Cordilleran
are "good" species. If good enough research ever comes out to show that
they aren't than the AOS will lump the species together like with Iceland
Gull. It isn't up to us to determine whether a species is good or not. We
just need to review the species that are currently valid.
3) If one thinks the spectrogram could be wrong, find examples of
intermediate spectrograms or any other that could show that this is not
the spectrogram of a Pacific-slope Flycatcher. It seems wrong to vote
against a record of any species due to one not knowing enough about the
species in question. There are plenty of resources, both in books and
online, that describe these species, their calls and their spectrograms. |

I commend
Kenny for his continued dogged pursuit of this record.
While my reservations regarding the taxonomy of this complex remain
unchanged, I am convinced by Rick's comments from the first review of this
record that the species is currently recognized by the AOU, so we should
review it as such.
Given that, and in spite of continuing reservations regarding the record,
especially having a very small sample size in the reference materials, and
my general skepticism regarding the reliability of vocalizations for
identification of these two species, I'll once again vote to accept this
record, as I did in the very first round.
The voice of this bird *sounds* more like "PSFL" to me, and the new
spectrograms seem to support that.
Since I´ve been "holding my nose" and calling PSFL and COFL by
vocalizations here in Mexico for years, I've decided that it would be
hypocritical to act differently in this forum. |

If this
species really exists, then I think this record is likely one of the
strongest cases we'll see for its occurrence in Utah, which is near
certain, considering the patterns in neighboring states.
Given that the AOU still considers this a species, I must assume a
submissive position with regards to my own opinions in the matter, and
simply hope for reason to prevail and some point in the future. |

Separating
a western fly in migration is still a problem as far as I'm concerned. I
agree they certainly come through Utah with regularity but with the
overlap in ranges could songs be learned from the opposite species? There
is certainly inter breeding going on.
Is it ok to add a sighting to the state list Just because we know they go
through the state?
I guess I wouldn't have a problem if it was added to the list but I can't
vote yes on it with what we have to work with.
I'm being stubborn and still going to call them Westerns for now. |

think the conclusions of the Andrew Rush study suggest this question is of

to suggest shelving this until a scientific consensus is achieved.

two of the previous record submission (i.e. 4 Dec 2015), are still sound.
I don't think it is possible to definitively be sure this isn't a
Cordilleran with Pacific-slope type calls or a hybrid of the two species,
based on the literature/studies referenced.

I'm reluctantly voting to accept, since it's a
single observer record without a photograph, and I believe we should have
stronger evidence for a state-first record. I'm hoping someone will send
it to a second round.
However, the description doesn't really fit anything else, and the
location and date make sense for any occurrence of this species in Utah. |
2nd round: |

I'm not comfortable with accepting a first state
record based upon a single observer, and it looks like other committee
members will ensure that the record is not accepted.
However, I'm convinced that what the observer describes is a Black-backed
Woodpecker, and so, perhaps, some effort should be made to look for that
species in the are where this was sighted.
Although some have stated that Williamson's Sapsucker was not eliminated
by the description, I find it difficult to see how it could be a
Williamson's when the observer noted white outer tail feathers (that
Williamson's doesn't have) as the bird flew away, and failed to note the
large white rump patch of Williamson's, that would be impossible to not
see in that view. Also, the lack of any color other than black and white
on the head doesn't fit male Williamson's.
So, I believe this record to be true, but perhaps it doesn't fulfill the
standards required of a first-state record. |

As a state first, this bird may not meet the
criteria of inclusion on the state list without further evidence, but I
leave that to the webmaster. Since it was passed to us to evaluate and
vote upon, I shall do so.
I went back and forth on this record, since the species has, to my
knowledge, never even been reported to occur in Utah. Ms. Mixa makes a
compelling argument for considering the species despite its previous
absence from our radar screens.
At first, the description of two white lines going around the neck made me
question the ID (in favor of a melanistic Three-toed), but then I re-read
the record and realized she was likely referring to the white on the
throat extending around the side of the neck. I don't see anything in this
record that would suggest anything but a Black-backed woodpecker. Amazing
sighting. |
2nd round: |

I still believe the description is of a Am. BB woodpecker.
I also believe our job is to vote on whether the species is the one
reported, as with any species. The question of whether the species should
be added to our list is a SEPARATE consideration dictated by our
acceptance criteria for state firsts. In my opinion, inclusion on the list
should be decided by the Secretary based on that criteria. If this is NOT
the case, then why are we even bothering to vote on these birds without
photos, etc? Perhaps there should be an option in the vote pull-down menu
that says something like "ACCEPT -- but does not meet criteria for
inclusion on state list." But to simply say "not adequate for state first"
makes no sense to me. |
