A Plover was found in Mass. yesterday that had a lot of birders coming out
in a driving rain for a look. Consensus is that it is a bright American
Golden, but take a look at the yellow of the head and supercilium, and the
dark auricular patch. The overall appearance was even more yellow live than
the photos indicate.

Steve,
The photos show a classic juvenile American Golden Plover.
The primary projection and relative position of the tertials to the tail and the
cold greyish appearance are typical.
Some AGP do show yellowish tones, but there is nothing here to really suggest an
alternative id as a Pacific or European Golden Plover.

First and foremost I would like to congratulate Paul and George since I
don't think there can be any doubt that this bird is a Phylloscopus
trochilus! However they want more, they want the first acredula or
yakutensis for America. Let me therefore quote Lars Svensson (Stockholm
1992, Identification Guide to European Passerines) when he challenges us
Europeans over yakutensis: ' and who would dare to claim one -some acredula
can look just the same'. And the means of proving it are very restricted
indeed, in fact restricted to the extreme wing-lengths measured in
yakutensis. Since Paul and George forgot to trap the wee bird we shall never
know for sure. On the other hand this bird looks exactly like a yakutensis
and therefore exactly like an acredula that looks exactly like a yakutensis
as well and it sure as hell doesn't look like our West European trochilus!

Subject: Re: Willow Warbler pix
From: Colin Bradshaw <drcolin.bradshaw(AT)BTINTERNET.COM>

First of all this is a brilliant bird and is undoubtedly a Willow Warbler.
Secondly, whilst it may look 'northern or north-eastern' in the two still on
the website below, it doesn't on many other stills and on the video footage.
What I see on that is a bird that always shows some yellow below on the
throat and upperbreast. Depending on the background the upperparts can look
anything from dull green to greyish-brown. I'm not sure what the actual
color was. The birds that we call acredula or yakutensis in the UK showed
virtually no yellow and very little green. They are esentially brown above
and cream below. They also show a very prominent supercilium that is lacking
in this bird.
Now the problem is that Willow Warbler is a very variable bird and it seems
likely that variation within races is at least as great as variation between
races. Many western European juvenile WW are only 1-2 shades duller than
Tennessee Warbler yet you can also get some that are the dull grey brown of
an immature Pine Warbler. Thus there are birds that breed in the UK that fit
our picture of yakutensis or acredula and there are birds in Siberia that
look like our picture of a W. European Willow Warbler. Thus it is likely
that, in the UK, we are ignoring many siberian willow warblers that are
indistinuishable from nominate and that some of the birds we assume come
from Siberia actually are local birds. The top and bottom is I don't think
you can tell which race this is as it looks not significantly different to
the birds I get in my local patch.
However, there is one exception. Its legs look slate grey to black in all
the photos I've seen and, whilst it does occur in Willow Warbler, it is a
very unusual feature. I've checked Williamson Ticehurst and De'mentiev &
Gladkov and none give leg coloration as a means of racial separation. I have
noticed however that, in Arctic Warbler wetsern European birds are
invariably pale legged but birds passing through NE China have about 1:5
with blackish legs. I don't know if a similar thing happens with Willow
Warbler.
I guess this can't be safely asigned to a race but it is an absoluter belter
no matter what race it was!

Subject: a long-winged fulva Plover
From: Martin Reid <upupa(AT)AIRMAIL.NET>
Date: 27 Oct 2002 7:35pm
Dear All,
I'll be chipping-in on the juv bird(s) soon, but I just got the URL of this
photo (thanks Kinjo):
http://www2.odn.ne.jp/wildbird/tidr12m.jpg - captioned "4/MAY/1991 Urawa
City, Saitama, Japan By M. Matsudo"
I think this lays to rest any doubts that long-winged fulva occur (and they
do so fairly often according to some in Australia); not the position of the
tertial tips in relation to the tail, which in combination with the P-tip
count beyond the tertial tip provide the strongest fulva feature. Note
also the less-than-lanky look of the legs! If this bird turned up in basic
plumage somewhere out of range, I wonder what it would be IDed as....
Cheers,
Martin

Subject: Status of the Eurasian Snipe on St. Lawrence and
St. Paul Islands, Alaska
From: Phil Davis <pdavis(AT)IX.NETCOM.COM>
Date: 27 Oct 2002 9:21pm
All -
The AOU recently split the Common Snipe into two species; Eurasian Snipe
(Gallinago gallinago) and Wilson's Snipe (Gallinago delicata). We know that
the Eurasian Snipe is common on Attu in the western Aleutians and is
reported to breed there. Since Attu is now relatively inaccessible to
birders, the question was raised about the status of these species in the
more accessible Bering Sea birding locations of Gambell and St. Paul.
I asked Dan Gibson of the University of Alaska what information he had with
regard to this question. Here is his response, which he agreed to allow me
to forward:
St. Lawrence Island:
"Fay and Cade (1959--the founding publication on the birds of St Lawrence
Island) reported no records of snipe, nor did Sealy et al. (1971), who
assembled the only synopsis published since. The meager data accumulated
here at University of Alaska Museum include scattered sightings (in
spring), some attributed by the observers to nominate gallinago [Eurasian
Snipe], some to delicata [Wilson's Snipe], and some unattributed. This
information is slim and does not point to annual occurrence of any/either
snipe there. The only specimen I know of from St Lawrence Island (from
Gambell) is here (UAM 5251, male, 17 May 1985, S. A. Klein). It is
Gallinago gallinago gallinago [Eurasian Snipe]."
Pribilofs:
"The story of snipe in the Pribilof Islands also got off to a slow start.
No Gallinago snipe was mentioned by Preble and McAtee (1923), the founding
publication there. The first record (Kenyon and Phillips 1965) was a
specimen that also provided the first Alaska and North American record of
nominate gallinago [Eurasian Snipe] (U. S. National Museum 463855, female,
5 September 1954, St Paul, R. E. Phillips). So far as I know there are
another 11 specimens of snipe from the Pribilofs (USNM 476165, male, 22 May
1961, St Paul, W. J. L. Sladen; USNM 476174, male, 14 September 1961, St
Paul, WJLS; USNM 479568, female, 22 May 1962, St Paul, WJLS and D. C.
Boggs; USNM 479569, male, 23 September 1962, St George, WJLS and DCB; USNM
495939, female, 16 September 1965, St Paul, R. L. DeLong; USNM 496835,
male, USNM 496839, female, USNM 496838, female, USNM 496836, male, and USNM
496837, male--five collected 20-26 May 1966, St George, RLD; and SCK
[Southwestern College, Winfield, Kansas] 1254, female, 17 May 1968, St
George, M. C. Thompson). These are all Gallinago gallinago gallinago
[Eurasian Snipe]. There have been reports of individual snipe identified by
experienced observers as delicata, but so far as I know there is no
substantiated record of Wilson's Snipe in the Pribilof Islands.
"I hope this information helps answer your question."
[Literature citations deleted: PD]
So, it would seem that statistically St. Paul is the better bet for finding
Eurasian Snipe. However, I am aware of two snipe sight reports from Gambell
this past spring; one was reported as Eurasian, the other was not
identified to subspecies (this was before the split).
Thanks, Dan.

In my previous message I used the term "Eurasian Snipe" for G. gallinago.
Ian Paulsen reminded me that the AOU retained the name "Common Snipe" for
G. gallinago. My bad ... Thanks, Ian.

The upper Midwest is known for rare but regular fall occurrences of mostly
indeterminate plumaged Plegadis Ibis. One present in western Wisconsin has
been designated as a Glossy based on what observers feel is a pale bluish
softpart pattern around the eye. Your comments would be most appreciated.

George:
If the very dark leg coloration in this photo is accurate, then this bird
would be very similar to those I've seen in Japan. 4 out of 4 Willow
Warblers (incl. this one) from extreme E. Asia I've seen (in the field or
photos) have had all dark legs. This is a much higher proportion than what I
would see in the UK and my guess is that it's a normal feature of NE Asian
Willow Warblers. Since Yakutensis is supposed to have very pale legs I guess
these birds are not this race. My understanding is that most acredule are
supposed to have pale legs too. Perhaps there is a cline where the eastern
birds are darker legged.

Subject: Willow Warbler race
From: Julian Hough <Jrhough1(AT)AOL.COM>
Date: 28 Oct 2002 9:27am
Dear ID-F,
Due to the clinal variations in plumages of phylloscs across their range, I
would be hesistant to try and compartmentalize the racial id., especially since
many authorities (eg Svensson et al) caution about the overlap in appearance.
However, the photos of the Willow Warbler seem to show a more nominate-looking
bird, with the exception of the dark legs which are generally unusual in
European birds.
Yakutensis, at least from the literature, would lack any yellow tones and be
basically greyish and white. I think this is the perception of many UK birders
of how yakutensis would appear, and the photo of an alleged yakutensis trapped
this fall in Scandinavia seems to support this, so the Gambell bird is too
green and yellow. However, with no experience, can yakutensis look like the
Gambell bird IE. not grey and white?
The bird also has a long pp, even from my recollection of Willow Warbler, and
the dark legs, as Nick Lethaby mentioned, may indicate a bird from a NE Asian
population.
I also don't think it's an acredula. I saw an acredula-type last week in
Cornwall, UK It fitted previous acredula-types, being cold and grey with a
prominent whitish supercilium and only faint olive tones to the wings. No strong
yellow tones were apparent, contra the Gambell bird.
So, without having a lot of samples of yakutensis, your bird would not be out of
place in Europe, and would not be raced as either yakutensis or acredua in my
view.

I have seen photo's of fledglings from the Pechora delta look like the

pretty dark legs as well. You'll find the typical grey and white plumage in
Africa after they have flown 10.000 km's or so!

Subject: longspur question
From: KACastelein and DJLauten <birdsong(AT)HARBORSIDE.COM>
Date: 30 Oct 2002 7:43pm
The suggestion was made that this bird might be a Bobolink. I don't
think so because the cap is wrong (it is not black enough but is
distictly streaked), the nape is not pale enough and contrasting with
the cap, the stripe behind the eye is not dark enough, wing projection
look short to me, importantly the tail feathers are clearly not pointy,
and based on the info Alan originally noted the bird was not any bigger
than the Lapland Longspurs it was with. A Bobolink is not only a longer
bird, but more so it is a much chunkier bird (I am not sure if Alan gave
the total story behind this bird, including the fact that it was with
other longspurs and was the same shape and size). Also Alan never
mentioned that the bird gave any Bobolink type calls when it was in
flight, and I can't imagine Alan (who I know quite well) missing the
distinctive call of a Bobolink - or a Bobolink who didn't call while in
flight! Also Bobolinks in fall a much overall buffier than this bird
is, and Alan has stated that the belly was white, not buffy, which is
why they do not think it was a Smith's Longspur.
With that said, I believe the bird is a longspur, and I lean towards
Chestnut-collared based on the wing formula.

Dear all,
With all due respect to Julian, I find myself disagreeing with his
characterization that "The photos show a classic juvenile American Golden
Plover."
I do agree with his subsequent comments about wing length, and that there
this no good reason to call it anything but a dominica, but I feel that the
long, somewhat bulbous bill (extending well back behind the eye when
reversed) and the amount of clear yellow in the head (on an otherwise
typical-looking AMGP) are far, far from being classic dominica!
I'd also draw your attention to leg color and apparent length: I feel that
in Spring adults, leg color (and length) MAY be as useful in this
species-pair as it is with Great and Mongolian Sand Plovers - but I am
seeing too much overlap in juv. birds; any comments on this?
I thank the Mass. folks for bringing this dominica to our attention, as it
adds another small piece to the jigsaw in Pluvialis ID (or difficulties
therein!)
Regards,
Martin

To me this appears to be a drab, immature (presumably female)
Chestnut-collared Longspur.

Subject: Surf Scoter Summary
Here's the final summary of the irruption of Surf Scoters on the east side.
I've included the info on Long-tailed Duck and White-wing Scoter, even
though their numbers seem about normal, so as to show the magnitude of the
irruption. I believe that if these numbers were due to increased birders in
the field that the numbers of Long-tailed Ducks and White-wing Scoters
would have increased also. I hear there were 3 - BLACK SCOTERS on the
Kootenays in BC, so keep the binos handy.

In regard to Martin's statement, I take no offence, but I have noticed recently,
especially with "orange-billed" Tern photos posted to the listserv, that it is
easy to gain a false impression of colour and jizz with some pictures, depending
on quality and resolution.
Looking at the photos of the bird on my screen, I didn't get the impression of
any striking yellowness about the head: to me, on my screen, it shows as a
yellow-buff tint to the supercilium and paler areas of the head.
Also, I would not really describe the bill as bulbous;it appears fractionally
longer than some dominicas, but doesn't draw my attention.
Compared to the earlier individual Martin posted pictures of, I still feel that
this bird is not too unusal.
