Hi Brandon,
I believe this bird is a Tundra Swan. In all the photos, note the
border of the bare parts of the bill & the feathered area rises essentially
vertically from the bottom for most of the way up the face, then makes a
nearly right angle bend toward the eye. I understand this pattern is
diagnostic for Tundra Swans--at least in adults. On Trumpeter Swans, it
rises at a 45 degree angle toward the eye with no change in direction. I'm
not so sure this is the case for juvenile birds, though.
The bill does look large and in some photos does seem to show the convex
shape I associate with Trumpeter Swan, but all the same, my vote is for
Tundra--or possibly a hybrid.
Cheers,

Greetings All
I really need to take a longer look at this bird and compare it with a num=
ber of photos I took of young Trumps this past weekend
Unfortunately, many of the pics are under or overexposed, making it hard=
to judge the bird's color. Most young Trumps are quite dark this time of=
year, with very limited area of white feathering, if any at all. In many=
pics, this bird seems to have too much white, or just be too pale, for a=
Trump.
I am not sure how reliable the facial feathering is on youngsters. I've no=
t been able to apply this mark nearly as well to immatures as adults.
The bill in most photos looks too delicate for a Trump to me, though more=
robust than many immature Tundras.
So, I lean strongly toward Tundra on this bird
Best Wishes
Steven Mlodinow

I agree that this is a Tundra Swan. The bill seems shorter than I
expect on a Trumpeter, the eye has a more prominent pale "ring" than
usual, the back is more rounded, and the bird appears to have molted a
few wing coverts. The shape of the edge of the feathers at the base of
the bill mentioned by Rob, as he suggests, doesn't work for juveniles.
Juvenile Trumpeters regularly show a Tundra like shape. I posted a
couple photos of representative individuals at:

Hi,
I recently found a Blackpoll Warbler in the south of Peru, and that =
would be the first record for the Manu Biosphere Reserve (who already =
have more than 1000 species on his list!).
3 pictures here:
http://www.flickr.com/photos/fabrice-schmitt/sets/72157622966241332/detai=
l/
The bird is in basic plumage, but the difference between male/female =
HY/SY 1st basic, and female AHY basic, doesn't seem to be obvious...
I don't see any molt limit so I think it is a AHY female.
Any help for the determination of the age and sexe of this bird would be =
very apreciated.
have good birding

Subject: Black Scoter study
From: Ian Paulsen <birdbooker(AT)ZIPCON.NET>
Date: 9 Dec 2009 10:53am
HI ALL:
Saw this on another listserver:
This will be of interest to many - published by George Sangster today.
The Wilson Journal of Ornithology 121(4):696-702, 2009
ACOUSTIC DIFFERENCES BETWEEN THE SCOTERS MELANITTA NIGRA NIGRA AND M. N.
AMERICANA.
ABSTRACT.-Scoter vocalizations may have a role in pair formation and pair
bonding. I compared the courtship calls of male Black Scoters (Melanitta
nigra nigra and M. n. americana) using published and archived recordings.
Courtship calls of the two subspecies differed diagnosably in duration. In
contrast, recordings from different localities within the ranges of each
taxon showed no diagnosable differentiation. This finding represents the
first indication these taxa differ in characters other than bill
morphology and supports recent proposals to treat M. n. americana as a
distinct species (M. americana). Vocal displays, in contrast to courtship
displays, of anatids have not been used for assessment of species limits
in Anatidae. My results indicate vocalizations are a potentially useful
additional character in species-level taxonomy of anatids.
Are there any records of the Eurasian Black Scoter in North America
(besides in Greenland)?

As nobody seems to have replied, here is a simplified version of Sanger's
results.
The courtship call of both species is a single repeated note. That of
nigra is very short, lasting about a tenth of a second. Sanger transcribes
it as a short, "pju or "pjut" with an abruptly lower-pitched ending.
The call of americana is much longer, each note averaging more than half a
second. Sanger transcribes it as a mournful "whuuuuw, huuuw" or "huuwuw."
It often has a slight rise in pitch either at the beginning, middle or end
which does not occur in nigra. It is also much more variable than the
courtship call of nigra.

Joseph
Many thanks for your summary and apologies on my behalf. George Sangster
very kindly emailed me a Pdf copy of his scientific work, as did Martin
Collinson, and I am currently working my way through it, attempting to
understand the main differencies in vocalisations. I have always been a great
proponent of this particular 'split', after seeing large numbers of American
Black, American White-winged and Surf Scoters in San Francisco many winters
ago, and of course after seeing some of our vagrant birds on this side of the
Atlantic, including one drake which survived for over seven years in North
Wales.
I am assuming George will find equal differencies in vocalisations between
American and Asiatic White-winged Scoters - both further forms
representative of specific merit in my opinion.
Very best wishes
Lee Evans

Subject: An odd duck
From: Will Russell <willrussell(AT)COMCAST.NET>
Date: 10 Dec 2009 11:47am
Good morning:
I received the following request from Staffan Rodebrand, a Swede who is the
organizational energy behind the Birding Azores website:
http://azores.seawatching.net/index.php?page=main
"Maybe you can give us some help from "over there". This autumn there was an
exceptional influx of (mostly first-year birds) Blue-winged Teal to the
Azores. Among them there was a strange bird showing characters of Cinnamon
Teal. See photos at:
http://azores.seawatching.net/index.php?page=rarebirdref&id=54#NotFirst (WR
note: scroll to bottom of the page; click on camera icon to the right of the
record date)
Maybe you can forward this mail, or give us information of some expert in
these birds in North America that can help us with the identification?"
I responded as follows: " I agree the bird’s odd and I’m not sure about
those rufous areas but this bird doesn’t look like a Cinnamon Teal to me;
the face pattern is just too pronounced. I assume this is a first winter
bird, and first winter Cinnamon’s have more of a face pattern than adults
which are plain faced, but typically the brownish tones in Cinnamons of this
age are understated and uniform across the head and body, not patchy or
limited to the underparts as they seem to be in your bird.
I wonder if the rufous isn't a stain of some kind (even the tail appears
rufous in one image, an area not rufous on Cinnamon Teal of any age)
although there are some scapulars that seem as if they’re rufous edged and
if correct that’s hard to explain with a stain theory. It is a big-billed
bird too but I would judge not out of the range of male Blue-winged Teal."
If there's a real expert reading this, perhaps they could respond to Staffan

Subject: An Interesting Pipit in Chicago
From: =?ISO-8859-1?Q?Greg_Neise?= <gregneise(AT)ILBIRDS.COM>
Date: 10 Dec 2009 3:28pm
Hi all,
I'm not sure what to make of this bird...I think it's an American Pipit (at
least I can't think of what else it might be offhand). I first noticed it
among a group of 8-10 American Pipits, and I thought I had a Yellow-rumped
Warbler for a second. It was smaller than the other pipits, with a shorter
tail, it fluttered more than it walked...and didn't walk with the typical,
long-necked "pigeon stride" that American Pipits have. It did not bob it's
tail while I was watching it.
But the plumage is what really made it stand out: it was gray, with a
distinctly streaked back and crown. White underparts with crisp streaks
forming a short necklace (forming a distinct white throat), distinct whitish
wingbars, tail had 2 outer retrices white all the way to the base. The bill
was also brighter yellow than the other Pipits and the legs appeared a bit
paler, but not flesh-colored (as in Red-throated). Lastly, whenever this
bird got near the American Pipits, they chased it away.

Subject: Rusty Blackbird v. Variant Brewer's

----INCLUDING text/plain MIME SECTION----
All:
While birding at White Rock Lake in Dallas, TX today I had good looks (at l=
east of the upperside and head) of a Rusty or variant Brewer's Blackbird. T=
he bird had extensive buffy/brown mottling all over the head, throat, upper=
breast, upper back and scapulars. However, there were no rusty edges to the=
tertials, wing-coverts, or upper-tailed coverts. The tertials at least wer=
e a glossy black. Size wise the bird looked perhaps a bit more compact that=
a typical Brewer's (which I see commonly in CA) and was markedly smaller t=
han a Common Grackle. Having looked through a bunch of photos, my impressio=
n is that male Rusty Blackbirds can be almost all black on the tertials and=
wing-coverts event by early October so I am guessing that my bird was in f=
act a male Rusty. However, I'd appreciate if others with more experience of=
Rusty Blackbirds can confirm that males can appear this way by early Decem=
ber. The checklist for the site lists Rusty as rare and Brewer's as unrecor=
ded, so Rusty is more likely and the bird was in flooded bottomland woodlan=
d, which is allegedly the preferred habitat of Rusty (in CA I've only seen=
them in supermarket parking lots!). However if I found such a bird in CA, =
I'm not sure what I would make of it, since my understanding was that rusty=
tertial edges were needed to rule out variant Brewer's Blackbirds.

Definitely nothing to heckle about here, this is indeed an interesting bird
and you should be commended for picking it out of the crowd. I have seen a
few like this here in California (have photos of a very similar bird), and I
haven't been sure what to do with them. If I recall correctly, this bird is
similar to one from British Columbia that was posted months ago on ID
Frontiers. In some ways it looks like pale* japonicus* (whitish ground
color, distinct markings below, paler legs), but it doesn't have enough to
make it a classic example. Paul Lehman often sees a few birds up at Gambell
that he calls "Tweeners" because they don't fit the classic mold for *
japonicus* or *pacificus*, but I'll let him chime in about those. I asked a
while ago about variation in *alticola* and didn't hear much back. My guess
is that there is great variation within and across subspecies, and these
pale extremes might occur rarely in all of them. I know, that's the easy way
out! More study needed!

Date: 11 Dec 2009 7:45am
I've done a bit more research, and had some help from friends whose
libraries are more complete than my own concerning European birds, and
discovered that this bird bears a striking resemblance to immature Water
Pipit (Anthus spinoletta).
A few things that stand out:
Overall grayish color.
Buffy auricular contrasting with gray/white head and nape.
Lateral throat stripe same color and tone as the upperparts, not darker.
Crisp blackish streaking on crown and mantle.
Black-centered median coverts with bold white fringes.
Distinct white wing bars.
Whitish malar wrapping around behind the auricular.
Necklace of streaks defining a clean white throat.
Lower mandible yellow nearly to the tip.
Leg color looks to be identical.
I've put together some comparison photos:
http://www.ilbirds.com/index.php?topic=30158.msg37416#msg37416
I would very very much appreciate especially the input of people in Europe
who may be familiar with Water Pipits.

Dear all,
I'm by no mean expert on the variation of Buff-bellied Pipits, having seen a few
japonicus and two rubescens in the field. But I've spent a bit of time looking
at my locally wintering Water Pipit, and if I ever saw a bird like yours here, I
would get really really excited...
Based on my limited experience, I can't offer any explanation on why this
individual looks different from "normal" rubescens, but to me it looks more like
American Buff-bellied Pipit than anything else. It does not have the
"Meadow-Pipit like" look of japonicus and does not look like spinoletta (or
petrosus). I would certainly bet on an American Buff-Bellied Pipit ...
Hope this helps,

Subject: Re: An Interesting Pipit in Chicago (Water
Pipit?)
From: Julian Hough <jrhough1(AT)SNET.NET>

Greg,
Your bird has some characters of "japonicus" -greyer, whiter-fringes to
median coverts and red-brown legs and looks grayer overall, but I don't have
any experience of japonicus and so can't really comment any further. I have
seen several rubescens that have looked paler-legged and slightly grayer,
but your bird seems colder in tone than any I have seen. It would definitely
be a bird I'd take a closer look at if I found this in the field.
However, my feeling is it's a weird rubescens, since it doesn't seem to fit
into anything I know (except maybe japonicus, but I'll leave that to others
to explain more succinctly why it is or isn't). I do not think it's a Water
Pipit of any of the European races. They are quite a sturdy bird, with a
longish bill and typically show dusky lores (lacking in the Chicago bird)
which contrast with a rather distinct whitish supercilium. Combined with
pale malar areas and pale throat, the head pattern is typically more
contrasting than rubescens.
Best,

Subject: Re: [BIRDWG01] An Interesting Pipit in Chicago (Water Pipit?)
I've done a bit more research, and had some help from friends whose
libraries are more complete than my own concerning European birds, and
discovered that this bird bears a striking resemblance to immature Water
Pipit (Anthus spinoletta).
A few things that stand out:
Overall grayish color.
Buffy auricular contrasting with gray/white head and nape.
Lateral throat stripe same color and tone as the upperparts, not darker.
Crisp blackish streaking on crown and mantle.
Black-centered median coverts with bold white fringes.
Distinct white wing bars.
Whitish malar wrapping around behind the auricular.
Necklace of streaks defining a clean white throat.
Lower mandible yellow nearly to the tip.
Leg color looks to be identical.
I've put together some comparison photos:

I would very very much appreciate especially the input of people in Europe
who may be familiar with Water Pipits.

Because the spinoletta from Japan are japonicus BBPipits, not spinoletta :)))
The explanation is that japonicus (like rubescens) has long been treated as
subspecies of Water Pipit Anthus spinoletta. Hence the confusion (I suppose) in
picture legends...
But I can see only japonicus on the pictures from Japan that you have added to
your site...

Amazing what happens when someone turns on the lights!
With my resources limited to the internet (as far as this group goes), I had
been operating under the assumption that these were all spinoletta!
Well then, it does seem to me that this bird could fit within A. r.
japonicus, except for a possibility of A. spinoletta blakistoni, which I
have found very little information about.
Thanks again,

One other thing that is clearly visible in the photos of the Chicago bird,
but I don't know if it's important, is that the two outer tail feathers (R6
and R5) have white outer webs all the way to the base.

I suspect your bird is a variant American Buff-bellied Pipit (rubescens).
It does not appear to be a Water Pipit of any form.
There is some overlap in the features of both japonicus and rubescens and
Paul Lehman speculated that birds in the Bering Sea area may be intergrades
between the two populations.
American Buff-bellied Pipit (hereafter ABBP) varies from being
plain-mantled and olive-toned, with a distinct GREY CAST. Siberian Buff-bellied
Pipit
(hereafter SBBP) has similar upperparts, but are often darker in tone and
more browner in general colouration. It also has a much whiter supercilium
and eye-ring and more contrasting whiter underparts. In comparison, ABBP is
generally more extensively buff below, with this colour extending to the
supercilium and eye-ring. Often, the eye-ring of japonicus is more striking
and obvious.
The tips of the median and greater coverts of ABBP are buffish and diff
usely demarcated, whilst in SBBP, the tips are distinctly whitish and much
more clear cut and defined. ABBP has mid to dark brown streaking, short and
often diffuse, often blurred together on the breast and extending in narrower
streaks down the flanks. The breast streaking on SBBP are normally very
dark chocolate-brown or blackish, generally broader, better defined and
sometimes even spotted-like. The underparts are overall much more contrasting.
The leg colour is usually distinctly different between the two species.
Rubescens have very dark leg colour, varying from dark reddish-brown to black,
whilst in japonicus the leg colour averages much paler, being pinkish or
pale brown, but exceptionally black.
The tail pattern of both species is somewhat variable (as in most pipit
species) but rubescens averages more white on t5 (the second to outer-most
feather) and often has a white tip to t4.
To the trained ear, there are subtle differences in calls: ABBP has a
somewhat Meadow Pipit-like 'tsip' note, often repeated five or six times, whilst
SBBP has a much more 'buzzy' tone to it, often uttered just once.
So, in summary, it ought to be possible to identify an either/or on 1) the
base colour of the underparts; 2) the facial pattern; 3) the colour of the
wing-bars; 4) the extent and colour of the underpart streaking and 5)
colour of its legs.
SEPARATION OF AMERICAN BUFF-BELLIED PIPIT FROM WATER PIPIT
Should be relatively straightforward. Water Pipit is a larger and more
robust bird. It has a larger, heavier bill and shows a whitish eye-ring that is
invariably broken, at least in front of the eye. This combines with dark
lores and a darker eye-stripe to give a somewhat aggressive appearance,
quite unlike the plain, open-faced expression of rubescens. The moustachial
stripe is also much weaker. The crown and nape are distinctly greyer than the
mantle in Water Pipit, and lack the olive tones, whilst the rump and
uppertail coverts are prominently warm-toned (in ABBP, the rump is concolorous
with the upperparts). The tail and tertials are consistently blacker in ABBP
and the flight calls are noticeably different - a weak, slightly drawn out
'veeestt' in Water Pipit.

Hi Caleb,
=A0=A0=A0 Many thanks for bringing this to my attention. I had received the=
initial correspondence from the ID Frontiers mailing group, but had yet to=
get around to opening the link to the site with images of the bird.
=A0=A0=A0 This challenge, to me, is interesting as, whereas you are approac=
hing it from a position of never having seen a Palearctic pipit, I am comin=
g at this with a limited understanding of variation within Buff-bellied ('A=
merican') Pipit, having seen around 5 vagrants over here. I find it hard, t=
herefore, to be authoritative, but I'll let you know what I think anyway.
=A0=A0=A0=A0 First off, I think we can safely say that this is one of the R=
ock/Water/Buff-bellied complex: all of the small pipits can be ruled out on=
at least one or two features, with Meadow, Tree, Red-throated and Pechora =
being more heavily marked above than the subject bird, especially so in=A0t=
he case of the latter two, Olive-backed having a different head pattern, ol=
ive-toned upperparts etc, Tree and Olive-backed having darker lores, and so=
on. It's also very obviously not one of the large pipits (Richard's/Tawny/=
Blyth's), for so many reasons.
=A0=A0=A0 On first glance, therefore, the white underparts may give rise to=
hopes of Water, but this bird would look quite odd, at least when compared=
to nominate western birds. The apparently white outer tail feathers, limit=
ed narrow streaking on the flanks etc, also the pale lores and other subtle=
features of the head pattern, would appear to exclude even the occasional =
pale, greyish Rock Pipit (either taxon), and the pale lores, exact nature o=
f the upperparts markings and such are also wrong for nominate Water Pipit.=
The head pattern, coupled with a thicker bill than on Rock, of nominate Wa=
ter in winter (basic) plumage almost reminds me of a Redwing, though I conc=
ede that this is somewhat fanciful.
=A0=A0=A0=A0 So far, so good, but it should be remembered that there are tw=
o other taxa included in Water Pipit: coutelli and blakistoni. The former i=
s more heavily streaked above than the nominate, and also has dark lores, s=
o is not a valid option here, but blakistoni often has paler lores, perhaps=
more limited flank streaking, and tends to be poorly marked on the upperpa=
rts. I can't find much information on this taxon, but there are some pics a=
bout half way down at http://wrightswanderings.blogspot.com/2008_12_01_arch=
ive.html.=20
=A0=A0=A0=A0 These birds, photographed at Beidaihe in October, do look diff=
erent from Water Pipits that I am used to (I saw no Water Pipits in China m=
yself, in May), but they still show many features that I would associate wi=
th the species, such as a brown rump, contrast between a greyer nape and br=
own mantle (more pronounced, apparently, in blakistoni than on spinoletta, =
and it seems to be the case based on this small sample size), and even the =
head pattern, while the lores are paler, does appear closer to nominate Wat=
er than that of the subject bird does, it could be argued.
=A0=A0=A0=A0 To be honest, and I appreciate that this is where I have to ki=
nd of follow a 'gut instinct' to some degree, the mystery bird most reminds=
me of an American Pipit of some taxon: the head pattern, general shape, na=
ture of the dark markings to the upperparts, visible white on the tail feat=
hers, bill shape/colour, nature of the flank streaking all seem reminiscent=
of this species to me, and, while I concede that the colour is most odd, s=
urely an aberrant American Pipit is more likely than a non-classic blakisto=
ni Water Pipit, especially since some features of the bird appear closer to=
the former than the latter anyway?
=A0=A0=A0=A0A very interesting bird, all the same, whatever happens in the =
end with it.

Here in California we have been identifying birds like this
japonicus. Although it lacks the bold black upperpart streaks that
some birds can show, I believe that some japonicus have less distinct
streaking, perhaps first-cycle and/or females. I have seen 6-8 and
there seems to be a clear separation between this group and the other
American subspecies, with few or no intermediates. This bird reminds
me a lot of one I saw in northern Baja California last winter, which
I had no problem submitting as japonicus.

From: Cape Romain Bird Observatory <crbo(AT)DMZS.COM>

Nick,
To me, it sounds like you had a Rusty Blackbird.
The large amount of rusty edging you describe sounds like a lot more
than I ever saw on (first year basic-plumaged) male Brewer's Blackbirds
I encountered during my years in California. I don't know if this is a
solid field mark; I would appreciate hearing more on this point from our
western friends.
Rusty Blackbirds can indeed appear the way you describe by early
December and even by November, in my experience.
One thing to keep in mind is that basic-plumaged male RUBL vary a LOT
in: A) the degree to which rusty feather edgings are present and B) how
rapidly the rusty edgings wear away. My understanding is that some
older males - even in fairly fresh basic plumage - do not show much
rusty edging at all.
This variability also applies to rusty edgings on the tertials and
wing-coverts. On the other end of the spectrum from your bird, I have
seen male RUBL still showing a bit of rusty edgings to the tertials in
mid-February. A couple of examples of this are below, though I have
seen much more pronounced cases at similar times of year.
One bird:

Another bird:

As an example of how much male RUBL can vary in how fast they wear out
their rusty feather edgings, check out these photos - both taken the
same day in mid-February while banding RUBL:

For what it's worth, there are other clues besides plumage - thickness
of bill, leg length, and tail length - but those are somewhat subjective
(particularly leg and tail length).

Subject: Rusty Blackbird v. Variant Brewer's

All:
While birding at White Rock Lake in Dallas, TX today I had good looks
(at least of the upperside and head) of a Rusty or variant Brewer's
Blackbird. The bird had extensive buffy/brown mottling all over the
head, throat, upperbreast, upper back and scapulars. However, there were
no rusty edges to the tertials, wing-coverts, or upper-tailed coverts.
The tertials at least were a glossy black.
Size wise the bird looked perhaps a bit more compact that a typical
Brewer's (which I see commonly in CA) and was markedly smaller than a
Common Grackle. Having looked through a bunch of photos, my impression
is that male Rusty Blackbirds can be almost all black on the tertials
and wing-coverts event by early October so I am guessing that my bird
was in fact a male Rusty.
However, I'd appreciate if others with more experience of Rusty
Blackbirds can confirm that males can appear this way by early December.
The checklist for the site lists Rusty as rare and Brewer's as
unrecorded, so Rusty is more likely and the bird was in flooded
bottomland woodland, which is allegedly the preferred habitat of Rusty
(in CA I've only seen them in supermarket parking lots!). However if I
found such a bird in CA, I'm not sure what I would make of it, since my
understanding was that rusty tertial edges were needed to rule out
variant Brewer's Blackbirds.

Hi all,
After spending most of the last 24 hours going over all of the detailed
information sent to me by members of this list, and the reference material
suggested or sent along, I have submitted this sighting to the Illinois
Ornithological Records Committee as Siberian Buff-bellied Pipit, Anthus
rubescens japonicus.
This has been a wonderful educational experience for me, and I thank
everyone who responded.
Cheers,
-greg neise

ps- wouldn't it be neat to have an archive of threads like this with
pictures and discussion, organized by taxon, that could be browsed and
searched easily? I've been thinking about that quite a bit lately...

Greetings All
I don't have too much to add. This bird differs from "classic" japonicus=
in that the malar stripe is not as blackish as I'd expect. Same is true=
or the underpart streaking.
The Illinois bird does have a nice white eyering, some back streaking, pin=
ky legs, and fairly white wingbars, but all of these are within range of=
what I've seen in Buff-bellied Pipits, albiet not "typical." =20
When looking at Japanese and Korean websites, I would ID a fair number of=
presumed japonicus as Buff-bellied Pipits if I saw them in North America.=
I suspect we pass over some of these japonicus (and for that matter, they=
may not be reliably identifiable as japonicus in field, and so should be=
"looked over.") as Buff-bellied Pipits.
Best Wishes
Steve Mlodinow

Here in California we have been identifying birds like this japonicus. Alt=
hough it lacks the bold black upperpart streaks that some birds can show,=
I believe that some japonicus have less distinct streaking, perhaps first=
-cycle and/or females. I have seen 6-8 and there seems to be a clear separ=
ation between this group and the other American subspecies, with few or no=
intermediates. This bird reminds me a lot of one I saw in northern Baja=
California last winter, which I had no problem submitting as japonicus.=

A final note about the photographs.
One of the inherent problems with the little ultrazoom cameras, like the
FZ18 that I use, is that they are consumer products, and the image sensor
just can't handle bright, high-contrast subjects as well as a DSLR. I had
adjusted the exposure to what I felt was as close as I could get, but one
thing has been nagging at me, and that is the bird's malar area.
When I first saw this bird, my immediate reaction was "yellow-rumped
warbler". The reason for that was the bird's overall gray tones, heavy
streaking on the chest, and a heavy dark mark on the upper breast/malar/side
of neck area and clean white throat. It really stood out, giving the
impression of the glommed up streaking on the upper breast of a breeding
Yellow-rumped Warbler. Of course, in the very next second, I realized it was
a pipit...but the photos as I have them on the forum—even though I feel that
they give the best overall impression of the bird—failed to exhibit that
mark which first got my attention.
The other thing about the photos I've noticed is that the bird's plumage
seems reflective. The sun was directly behind me (at 1PM, when I found the
bird), and low in the sky (being mid-December). If you look at the images
I've attached to this email, you'll notice that in image _5646 the median
coverts seem gray with rather broad pale gray fringes. But if you look at
image _5643, where the bird has shifted slightly and is now at an angle to
the sun, the median coverts appear as I saw them in the field: black
centered with broad white fringes.
The same goes for the upper breast/malar markings. In the two images that
best show this, the bird is flat to the sun and the breast is blown out, and
the dark markings washed out (_5646a). In image _5646, I've adjusted the
exposure so that this appears more like it did in the field, but because of
the limited amount of image data caused by the high contrast subject, the
image "blocks up" a little, and renders the legs darker than they appeared
in the field.
What I saw, what I think the photographs depict, and why I think that this
bird is japonicus, are:
Lateral throat stripe thick and blocky, appearing spotted and extending to
the rear of the auricular.
Crisp blackish streaking on crown and mantle.
White eye-ring
Clean white underparts, with dark gray to blackish streaking, that almost
looked spotted.
Black-centered median coverts with bold white fringes.
Greater coverts with well defined light gray-to-white fringes, forming
distinct white wing bars.
Whitish "moustache-stripe" wrapping around behind the auricular.
Necklace of blocky, almost spotted, streaks defining a clean white throat.
Pale lores.
Lower mandible yellow nearly to the tip.
Leg color dark yellow/pale brown.
