Well, seeing as a relatively drab female is unlikely to be an escapee from
the pet trade, this should put to rest some of the angst about the status
of the Fish Springs record. Nice work, Rick. |

2008-24 Yellow-bellied Flycatcher
Evaluator |

No, ID |
There is not enough detail in either the description or the photos to
support a definitive identification of a vagrant Empidonax flycatcher.
Confirming the identification of an out-of-range Yellow-bellied Flycatcher
in the west is extremely difficult and usually requires extensive study
and often detailed photographs of subtle characteristics (e.g. spacing of
primaries, primary projection length, etc.).
With that said, there are several characteristics visible in the photos
that do not support the identification as a Yellow-bellied Flycatcher
(bill shape and length, lower mandible color, inconspicuous eye-ring,
whitish throat, yellow-olive back, primary projection, etc.), and very few
that would suggest a YB
Flycatcher. Yellow-bellied
Flycatchers are characterized as having a large, broad bill, yellow
/ orange lower mandible, conspicuous eye-ring, yellow throat, very green
back, yellowish underparts, and moderate primary projection. Perhaps the
biggest character that is incongruous with Yellow-bellied Flycatcher is
the crested crown shown in all three photos. I ve never observed a
Yellow-bellied Flycatcher with a crested or ragged crown. The head of a
Yellow-bellied Flycatcher, even on first-fall birds, should appear smooth
and round. According to Kaufman (1990), the crown of YB Flycatchers is
usually smoothly rounded, not crested or peaked . Alderfer and Dunn (2006)
de!
scribe the YB crown as rounded and not peaked or crested and Sibley
(2000) describes YB s with a rounded head and slight but not ragged
crest .
The description states that 10-15 pictures were taken. I would encourage
submitting all available photographs when trying to establish an extremely
difficult identification. |

There are many things that point
to this being a Yellow-bellied Flycatcher. However there are many
question. I don't believe I can really tell what the eye ring is like from
the photos. The head is obviously crested in all the photos. Kenn Kaufman
states in his Advanced Birding Guide, that this bird usually has a rounded
head, not crested or peaked. In addition he states that the bird usually
sticks to dense forest, even during migration. There are too many unknowns
with this bird for me to make a definitive ID. |

The observer had better views

such a difficult species. |

No, ID |
First, I have no experience with
Yellow-bellied Flycatcher. Second, it does seem to be the best fit for
this bird. However, I'm not sure this couldn't be a Least...although the
thin, relatively indistinct eye ring, overall coloration, and the bill
size and shape suggests otherwise. I'm not sure Acadian should have been
eliminated so quickly, but they do have a relatively long primary
projection, which does not appear to be the case for this bird via the
photos (and the observers note that it was short-medium). I would like to
see this go to the second round, and hopefully someone with more
experience has some useful thoughts because I don't think this bird is one
of our more common Utah empids. |

Kristin P. |
9 Jun 2009 |
No, ID |
The difficulty of defending a
non-singing Empid in migration out of habitat looms large considering the
similarity of Western
Flycatchers, plumage variability, the general wariness of the
review bird (preventing exceptional images necessary in this case), and
poor lighting. While several features favor Yellow-bellied, not all do and
I keep in mind that poor lighting affects not only the camera's images,
but it affects observers' perceptions as well. I don't think it's
realistic to compare differences in shades of color of two species of
Empids when one of the birds is not present and the lighting is poor. In
the category of extraordinary claims require extraordinary proof, I
believe a Yellow-bellied sight record requires a recording and/or
outstanding images and the bird/lighting/circumstances allowed none of
these. |
2nd round |
11 Aug 2009 |
No, ID |
Some IDs are just plain harder
to defend. While a recording of an Empid might be the conclusive evidence
needed to accept a record like this, the likelihood of obtaining a
recording of a Yellow-bellied Flycatcher in Utah, almost certainly to be a
bird on passage, is extremely low. My inclinations toward the narrative
info and photos are the same--not enough to ID this bird conclusively. |
Terry S. |
11 Dec 2008 |
No, ID |
The empidonax flycatchers can be
difficult to tell apart this time of year. Plumage differences due to
molt, wear and age sure make the plumage quite variable. I look at the
photos submitted and I am not convinced that this not a Western
Flycatcher. The bill seems larger than I would expect and the tail I
believe is not that short. The quality of the photos makes it difficult to
really see details of the bird including the eye-ring. I have seen several
western type flycatchers that have strong yellow washes that fall within
the range of this bird. |
Ron R. 2nd round |
5 Jul 2009 |
No, ID |
I don't feel there is enough
compelling support for this bird being a yellow-bellied flycatcher. Some
characteristics are supporting: greenish back, what appear to be almost
black wings that set off the wing-bars and tertials, round eye ring; while
others are not so supporting: faint eye-ring, grayish rather than yellow
throat, crested head (although this might simply be an agitated bird),
lack of strong greenish wash on sides of breast. Given that the ID is not
definitive (observations and photos taken under poor light conditions) and
the ID is based in part on trying to eliminate other species, I don't feel
this is a sufficient record for a tough species ID (without vocalization). |
Larry T. |
14 Dec 2008 |
No, ID |
This is a well done write up and
the bird could very well be a YBFL. But for a first state record on such a
difficult group a calling or in hand bird is almost a must. If the
description had said a yellow instead of pale
white eye ring that would have been very helpful too. |

I think everything but the eye ring are very suggestive of some plumage or
other of a Yellow-bellied flycatcher. The bill shape and color eliminate
most options, especially the eastern empids. The problem I am having is
definitively eliminating the yellower races of the Willow flycatcher (for
which the eye ring might fit best, but whose bills, in my opinion, should
be a bit longer than shown on the photos).
I at first thought this bird represented a worn fall adult of the
Yellow-bellied flycatcher, which is "allowed" a pale throat, but the very
broad "yellow-beige" wing bars make me wonder just how "worn" this
individual really is. Please, if there are Committee members out there who
are more familiar with the molt/wearing sequences of the different
portions of the respective empid species, do share your knowledge
(especially as regards the molt timing of the throat feathers vs. the wing
coverts). [see "NOTE ON MOLT" below for some background]
By the way, the fact that this bird appears to have a dark tip to its
lower mandible in no way eliminates it from consideration as a
Yellow-bellied flycatcher. Photos of this species can show quite a bit of
darkness there (more than this one).
I am reluctantly voting "NO" in hopes that this record will go into the
second round, but also because I am sufficiently unsure that this is
definitely a Yellow-bellied flycatcher (though that appears to me at this
time to be the best fit).
*****
NOTE ON MOLT:
(This is from Cornell's "The Birds of North America Online")
Basic I Plumage
Prebasic I (postjuvenal) molt partial; occurs Jul Sep, primarily on summer
grounds; unknown if molt is suspended for migration. Molt includes
body-feathers, most to all median wing-coverts, 0 (in approximately 22% of
individuals) to 7 inner greater wing-coverts and usually (approximately
89%) 1 3 tertials, but no rectrices.
Basic I plumage similar to Definitive Basic plumage, except shows
different molt limits. Retained outer wing-coverts tipped buffy brownish,
contrasting with fresher, duskier, and whitish to yellowish tipped,
replaced inner wing-coverts; 1 3 tertials usually contrastingly fresh;
outer primary-coverts narrower and relatively abraded, with reduced
greenish edges; primaries and secondaries even in wear, and rectrices
narrower and more tapered
Definitive Basic Plumage
Definitive Prebasic molt incomplete to complete; occurs Aug Oct on
wintering grounds. Body plumage and all or most flight feathers replaced;
1 6 inner secondaries (among S1 S7) and outermost 1 5 primaries (among P6
P10) sometimes retained. |

When I look at the dark color of the eye, the fact that the pale edging to
facial skin does not extend beyond eye, the blue tone to the facial skin,
and the lack of pink tones in the
pale face border, I
feel confident this is not a hybrid (at least not a first-generation
hybrid--who knows about back-crossing back toward Glossy ibis!). When one
compares this bird to the hybrids shown on the Plegadis website, the link
to which was provided by Colby, I think the differences listed above are
pretty dramatic.
Cliff Weisse, a bird expert in Idaho whose advice on our Birdtalk I've
come to greatly respect over the years, had a very good discussion on
differentiating the two species in May 2006. What I noted from the
discussion were the following points:
1) The pale edges of the facial skin on a Glossy should be pale blue, not
lavender. [To me, the edging appears white with no "warm" tones,
consistent with a Glossy.]
2) All hybrids Cliff has seen had a reddish tinge to the iris. This is
well illustrated in the Plegadis website sent by Colby.

Timing is appropriate and a Northern Parula, even a worn one, in San Juan
Co. on 24 May is certainly a possibility, but there is really very little
to go on in the description. Perhaps the description could be of a N.
Parula, but it ignores some important and diagnostic characters such as
eye-arcs rather than eyering, leg/foot color, bicolored bill, wing-bars,
etc. Accepting the assumption that the wing-bars 'were eliminated' through
wear, the remaining description (gray face and upperparts, faint eyering,
yellow throat and upper breast, white underparts, olive patch on back,
etc. certainly does not rule (and may better fit) a first-winter
Magnolia Warbler
(with delayed molt into first alternate plumage). |

It is unusual to see a bird this
worn looking in late May but it does happen. I would guess a first Spring
female retaining it's juvenile wing coverts explaining the lack of
wingbars. And the more of a faint eyering look over eye arcs would be from
a worn bird also.. Everything else about the description fits a Parula
fine. N. Parula is one of the more common eastern
Warblers in Spring. The 20+ year old notes and memory to go along
with this record are still convincing enough for me. |

I think of all the possible
Iceland Gulls we have reviewed this one seems to fit the

Thayer's and Iceland are the same species spread over a varibility cline
with Kumlien's somewhere in the middle. That aside and given they are
recognized as different species I believe the observers and done an
excellent job in detailing the characteristics of the bird. |

This is always a very difficult
pair to separate. There is a lot to take into consideration with the
variability in their plumage. But looking at the great pics and given the
time of year I can see nothing wrong with accepting this bird as a
Iceland. |

Boy, this is one of those that can be (and has been) well argued both
ways. I must admit I am not a gullophile, and I am generally skeptical of
the sanctity of species limits of gulls in general. Furthermore, I am not
convinced that, with the amount of hybridization that occurs in the genus
Larus, gulls are that certain either. So I am not sure one can ever be
100% certain of IDs within certain gull complexes such as this. Perhaps
the best one can do with certain gull IDs is to give it one's best shot.
So here goes.
In my analysis, I think the bird must be an Iceland, Glaucous, or Thayers
gull, based on overall paleness of body plumage, etc. I think Thayers can
be eliminated because even the palest Thayer's don't seem to be this pale,
especially on the flight
feathers and tail, even though its bill is a very good match. So
that leaves the first two, which parse out as follows:
Overall size: In the photos, the bird appears just barely larger than
California gulls around it. This strongly argues for an Iceland
gull, as Glaucous gulls are generally much larger (Sibley & Natl Geo say
California = 21", Iceland = 22", Thayer's = 23", and Glaucous = 27"; and
Peter Harrison's Seabirds guide gives the ranges of Calif = 51-58cm,
Thayer's = 56-63cm, Iceland = 58-64cm, Glaucous = 66-77cm). Based on
these measurements, the bird in question is too small to be a
Glaucous gull. But, according to Cliff Weisse's e-mail of 5 Nov
2008 on Utah's Birtalk, Howell & Dunn's measurements for the barrovianus
ssp of Glaucous gull is downright wee at 21.5-24.8", compared to 19-24.5"
for Iceland gull. So perhaps size is not such a good fieldmark as one
might think. [Note, the barrovianus ssp also has a smaller, more slender
bill, per literature]
Wing Extensions: The primaries extend far beyond the tail on this
bird--much longer than those shown in Kaufman, Natl Geo, and Sibley for
Glaucous gull, but match an Iceland gull quite well. This is a strong
argument in my opinion, as it shows proportions rather than just size.
Bill size: In general, Glaucous gulls should have much thicker and longer
bills than this bird, while Iceland bills match this bird quite well. But
note the Cautionary Note below. Photos of bills of Glaucous gulls I've
seen all look at least somewhat larger than this bird's.
Position of Legs: The legs on this bird are positioned farther back on
the body than guides say the Iceland gull should show. This is perhaps
the best evidence for this bird being a Glaucous gull. However, photos on
the web show several examples of
Iceland gulls with legs farther back on the body than shown in
those learned sketches in guides, and completely consistent with this
gull.
Head Shape: This bird has a round head, consistent with an Iceland gull.
Glaucous gulls tend to have blocker heads. But this is so subtle as to be
dangerous.
Cautionary note: Kaufman (in Advanced Birding) strongly cautions that the
size difference between sexes in some gulls, including Thayers, can be
dramatic. Likewise, females tend to have shorter, thinner bills and
smaller, rounder heads.
Bill Color: The Iceland gulls in 1st winter plumage tend to have more
uniformly dark bills, but there appears to be variation in this field
mark. Still, the bill color is a better (more typical) match for a
Glacous gull than an Iceland gull.
All this being said, photos I have seen on the internet of both Glaucous &
Iceland gulls show excellent matches to Iceland but not so much for
Glaucous.
So, to my mind the bird is a far better match for an Iceland gull than any
other species. In fact, I see nothing in this bird that would preclude it
being an Iceland gull, even if a couple of the fieldmarks push the limits
of the bell curve. |

I don't see how this can be anything but a Brown-capped Rosy-Finch.
Although there does seem to be a size disparity in some of the photos,
there doesn't seem to be any in other photos. I just think this must be
an illusion. |

The subject bird in Photos A and
B does appear slightly larger than the accompanying Black Rosy-Finches but
in the other photos the birds are all about the same size. There is
nothing in the photos to suggest the subject bird could be anything other
than a Brown-capped Rosy-Finch. |

I don't know what to say about
the size of the bird. I haven't any experience seeing the two species
side-by-side. It does look larger than the other birds in the first
photo. I did a quick search for Rosy-Finch measurements and could only
find the chart on this page.

The overall brown color, dark cap, lack of silver head band, extensive
pink on underside are diagnostic for this likely male individual. |

No, ID |
I thought this would be an easy ID and that I would vote to ACCEPT. Utah
is long overdue for this species, and I firmly believe we must surely be
visited by these birds on a regular basis, especially SE part of the
state.
I still think the bird is most like a Brown-capped rosy-finch. However, I
am very troubled by the seemingly large contrast in size between this
individual and the Black rosy-finches around it. This bird looks
significantly larger than those around it in all the photos. According to
the sources I consulted, the three species of American rosy-finches are
all about the same size with the exception of the Aleutian races, which
are significantly larger (14-16cm vs. 17-21cm per Cornell site).
Everything else about the bird seems to strongly point to or at least be
consistent with a Brown-capped rosy-finch, but the size issue troubles me
enough to attempt pushing it to the second round, with apologies.
For what it is worth, and I am not trying to be glib or clever here, I
also think the bird looks more like a Brown-capped rosy-finch than the
Siberian forms of rosy-finches which until recently were all lumped with
the American forms into the "Rosy finch." |

Having only seen this species clearly once in my life, and that without
other rosy finches on the mountain top to compare their size to, I have
been trying to figure out from books and internet sources how this size
difference could be so pronounced in so many of the photos included with
this record. I finally found this: "Black Rosy-Finches tend to be about
1/4 inch shorter from tip of bill to end of tail than the other species,
which are about 6 1/4 inches in length." Odd that this bit of knowledge
is not more widespread. Perhaps it is because there are so many
subspecies within this complex (esp. the Gray-crowned rosy finches) that
it is difficult to make size generalizations.
With this quote in mind, and after studying other possibilities vis-a-vis
the other field marks, I have decided to change my vote to ACCEPT. A long
overdue species, well documented. |

I am voting to accept this based on the wonderful photos, especially Photo
C of the first set and those of the second set by Mr. Avery & Binch,
rather than the near-absent (to put it kindly) description in the writeup.
For me, the most persuasive field marks observed from the photos are:
--bright orange-yellow legs of med length
--mostly-white underwing
--length & slightly decurved shape of bill
--shape of and length of tertials relative to primary projection
--white U-shaped pattern on uppertail coverts, and
--the slightly "scruffy" mantle. |
