All,

Ended up with 4 strong votes for Pacific and a couple of leans to Winter
(both from West Coast birders). I think it is a Pacific but a little off
from classic.

Thanks,

Nick

I concur-- this is a Pacific Wren.

Winter Wren is more of a "chimp" or "cheemp". This is very much a
"chik-chik" like Pacific.

All,

I was wondering if folks familiar with Winter and Pacific Wren can comment
on the audio in the ebird checklist: https://ebird.org/checklist/S7...

This bird was seen and recorded in southern California, where Pacific is
rare but regular and Winter Wren a vagrant. The bird responded very
strongly and consistently to Winter Wren playback (we used this because I
believe I saw one at the same spot a few weeks ago), but I have often
noted a response to playback from species that were not the same as
playback vocalization. This makes me wary of drawing too many conclusions
from getting a response.

Both times I have seen a second sighting of a Pacific/Winter Wren about 200
yards away that clearly appeared to be a Pacific and sounded different and
sharper to my ear than this recording. Having said that, I don't feel all
that confident that this recording is really dramatically different to a
Pacific Wren. IN addition, the plumage of this checklist bird falls well
within the range of Pacific.

Subject: winter empid from Davis, California: Dusky or Least?
Date: Wed Dec 23 2020 17:32 pm
From: garybnunn AT gmail.com
 
Hi Steve,

I would be in agreement with Nick on the identity of this Empid that as a
Least Flycatcher. I did take a look at the three links, sets of photos,
and I don't do Facebook so I have not seen the earlier discussion.

Relative tail length looks wrong to me for Dusky, has the more overall
compact effect seen in Least. Also the bill shape profile from beneath is
very good I think for Least, wider based a bit spatulate, Dusky would
appear longer and more spear shaped in my opinion.

Maybe not the most contrasty coverts and tertials but this seems a bit more
variable on Least than we actually like to accept here on the west coast :)

The whit calls obviously very similar but in my experience Least seems to
fire off a series of whits and Dusky usually emits single whit calls just
every now and then. I think the two species differ a bit also in behavior,
at least on my usual birding patch, Dusky often feeding out in the open
from 10--20 foot perches around edge of trees etc., this species seems to
like finding beetles on the ground from these perches I have noticed, you
will hear them whacking beetles back on a perch, while Least often more
hiding away disappearing between patches of thicker cover. So there might
be some subtle behavioral differences observers noted.

A link here to Least Flycatcher in San Diego, a comparable bill shape photo
maybe http://www.sandiegobirding.com...

Best, Gary Nunn

Subject: winter empid from Davis, California: Dusky or Least?
Date: Wed Dec 23 2020 17:07 pm
From: nlethaby AT gmail.com
 
Steve,

Although I don't see lots of either of these in coastal Southern
California, based on the set of excellent photos from Kirk Swenson, I would
confidently call this a Least. It certainly matches the birds I call Least
down here. The wings are pretty contrasting, although perhaps not as strong
as they could be, while the olive head and back, with the subtle gray wash
on the hindneck is very consistent with the half dozen (fall) Leasts I have
seen here and matches many birds I see in photos. Although I suspect Dusky
can look similar, my impression is that they tend to be more extensively on
the head and back. The extensively white throat, without any gray, is great
for Least and not so good for Dusky. The wing/tail ratio is better for
Least IMO. Dusky should look longer-tailed and with a shorter primary
projection (although the whole primary projection thing seems to vary a
bit). Finally the bill shape appears short and triangular, which fits
Least. Dusky should be longer and narrower.

I don't think the bill color is a problem at all. Many Least Flycatchers
show dark on the lower mandible like this. If you scroll through pictures
from Macauley from the east coast, you'll see plenty of Least Flycatchers
with dark on the lower mandible.

Subject: winter empid from Davis, California: Dusky or Least?
Date: Wed Dec 23 2020 15:37 pm
From: stevechampton AT gmail.com
 
This empid was found March 5, 2020 and was present thru April 2, so
possibly an over-wintering bird, in Davis, California (near Sacramento).
During this time of year, no empid is expected. It was seen by many,
photographed a lot, and its "whit" call recorded. It was widely thought by
all observers in the field to be a Dusky Flycatcher.

Recently, some have raised the possibility of Least Flycatcher. A
discussion on Advanced Bird ID on Facebook yielded some strong opinions but
no clear consensus. Discussion focused primarily on the "whit", the wing
panel, and the bill shape and color.

Both species have only 3-4 winter records in northern California on eBird,
so both are equally unexpected (though we have seen a marked increase in
overwintering neotropical migrants as our winters have warmed above the
freezing threshold).

You should look at the pics in all three links, as lighting and postures
vary.

with both species.

Hi Frank and all,

This is a kind of partial albinism - an absence of melanin on some
feathers. A typical winter goldfinch has a mixture of grayish/brownish
melanin pigments and yellow carotenoid pigments in each feather to produce
their rich color. The absence of melanin on some feathers reveals the
bright yellow carotenoid pigments (which are unaffected by albinism).

Best,
David

I have had one with the same odd coloration except that it is limited to a
band around the back of the head.

An odd-looking finch was seen at a Nyjer feeder in Cumberland County,
Pennsylvania a few days ago.

It has not been seen since.

My best guess is an aberrant American Goldfinch.

Very bad photos can be seen at http://franklinhaas.com/finch/...

Any thoughts?

Frank

Subject: FW: Unusual 'dark' goose (parvipes?) in Delaware County, PA

Hi,



I've heard that some can't view the photos. If so, try this link instead:

http://becard.blogspot.com/202...

I realize that this is probably not anything special. Just curious about
others' comments on it.



Thanks and Good birding,

Subject: Unusual 'dark' goose (parvipes?) in Delaware County, PA



Hi,



While photographing the Bean-Goose in Pennsylvania on December 16th, another
'dark' goose was noted near it. I read a LOT of articles and looked at a
LOT of photos and still can't really put a name to this one. The only thing
I can come up with is either a very dark Lesser Canada Goose (parvipes) or a
runt goose with an aberrant plumage of another subspecies. The bird is
dark, but doesn't have the chestnut or brownish tones of that of the 'Dusky'
form.

I have added the four better photos of this bird with a short written
description to my blog post about the Bean-Goose. They can be seen by
scrolling down past the Bean-Goose photos at:

https://becard.blogspot.com/20...

Since here in the east, we only see the 'Atlantic' form of Canada Goose with
the occasional "Richardson's" Cackling Goose mixed in, I'd be really
interested in hearing from some of the western birders who more regularly
see the western subspecies.

Subject: Guam gull ID helo
Date: Thu Dec 17 2020 3:42 am
From: dpratt14 AT nc.rr.com
 
Hi birders:

Gary Wiles and I are seeking help with the identification of a gull that was photographed in mid-October on Guam in Micronesia, where all species of gulls (except Black-headed) are quite rare. The only photos of it were taken on a cell phone camera and are therefore of low quality. They were apparently taken late in the day under cloudy conditions and may be underexposed. The bird shows entirely blackish upperparts, white underparts, white head and neck, a white tail, and a mostly(?) dark bill that looks huge in some shots, but not in others. A white trailing edge to the wing shows in flight but not on the perched bird, and we can discern no white spots in the outer primaries. We have some ideas of our own but need further advice before we make a call. We will appreciate any comments this group cares to make.

Seven photos of the bird can be viewed at https://spaces.hightail.com/sp...
