Everyone: I wanted to share this recent letter sent to me by Magill Weber
concerning the E. Willet from Texas. It has an enlarged photo that shows
that the bird is not oiled, but overloaded with black coloration to its
plumage. I have never seen anything like this with Eastern Willet in the
thousands of individuals that I have consciously studied over the last ten
years, so I will leave this one up to the scientists to work out. Kevin
Karlson
Magill,
You are right. It is not an oiled bird, but one that has an abundance of
black coloration to its plumage. I am not sure what caused this overload of
black coloration, and why it was distributed to the neck region, but it is
clearly a bird that has a bunch of black coloration where it does not belong
(including the head, face and flanks). Everything else is perfect for E.
Willet, so I will not stretch for a hybrid explanation, especially since
there are no shorebirds that nest anywhere near E. Willet's range that would
contribute to this aberrant coloration, especially Arctic breeding birds
like Ruff and Spotted Redshank. This is not a common occurrence in
shorebirds, as I have seen literally thousands of Eastern Willets from the
High Island to Galveston area of the upper Texas Coast. Kevin

Subject: Oiled Willet ID?
Kevin,
Definitely appreciate your response on the Willet ID, and totally agree with
your assessment that except for the black, its an eastern race Willet. I've
gotten lots of back-channels suggesting everything from hybrids (Redshank,
Ruff) to various godwits (I guess because of the redish tinge on the bill,
which I think is a halo effect from the poor light conditions), but I can't
see anything that is inconsistent with typical Willet.
But wanted to follow up a bit more, esp. since I used your guide as a
primary resource in an attempt to figure this beast out. I'm attaching the
link to the extra-large blow up of the pic.

As I mentioned in my original post, when we first saw the bird, we were
calling it the 'dirty Willet', assuming that it got into oil. But the
totally clean underside--I just can't figure out why that would be the case.
Check out the super enlargement--its not entirely consistent with oil, at
least in my experience--it looks too streaky, not 'stained'--like its
actually a plumage abberation. But have no idea how a hyperpigmentation
would look. Just wanted to get your take on it, enlarged a bit bigger.
This bird is giving me total headaches, but figured I'd ask you to take a
look one last time.
Thanks much!

To: BIRDWG01(AT)LISTSERV.ARIZONA.EDU
Magill and others,
This is clearly a breeding Eastern Willet of the Gulf Coast form, which
tends to be a bit paler and longer billed than the Atlantic Coast Eastern
Willets. After studying these Eastern Willets in the High Island/Galveston
area for the past seven years in March or April, I have found them to be
generally less heavily marked on the breast and back than the Atlantic E.
Willets that breed near my house in southern NJ. They also tend to have
longer bills overall, and often approach smaller Western Willets in bill
length and shape.
This bird is either oiled on the neck, or marked with another extraneous
dye, which is not out of the question, considering the oil fields that ring
Anahuac NWR. Both willets feed and bathe in the fresh water pools that are
associated with the oil fields, although I must admit that the coloration
looks fairly restricted to the upper breast and neck, and the bird would be
hard pressed to only get a stain in that area. I often bird the oil fields
near High Island, and have never seen an oiled Eastern Willet there. Maybe
it is an aberration in color or pigment in these areas, but either way, it
is a typical Eastern Willet.

Subject: [BIRDWG01] Willet ID
Curious to hear any comments on this shorebird, photographed several days
ago near Anhuac NWR, Texas. I observed the bird in poor early evening light
in a mixed flock of Willets, Whimbrel, and Marbled Godwits, and as the flock
flushed. Roughly Willet sized and shaped, bill consistent with Willet, no
good looks at underwings of this individual (blending in with a eastern race
Willet dominated flock). Our initial impression was that the bird had gotten
into some oil, but in looking at the dark patterning in the photo, crisp
facial appearance, and dark under the wings but showing a clean underside,
this would be an unlikely result. The bird was relocated and photographed
the next day (see single photo), but I have no additional information from
that observation, except that it again flushed quickly. (Classic example of
shooting photos first, and getting lazy with field notes, particularly
around skittish flocks. I'll be the first to take the blame for that one.)
Note the oddly dark 'ring' around the neck and back (shown in the
photograph) and dark legs. Unfortunately this is the best photo my group
has put their hands on, thus far. I'd appreciate any comments or other
observations of this type of molt patterning or dark-necked appearance.
Could this just be an oiled bird? Any other explanation?

Folks

I am just back from my fourth and very successful tour of the Lesser
Antilles. Among the many amazing birds seen we followed up on a sighting =
of
a Roseate Spoonbill in St. Lucia and surprisingly realized that the bird =
was
a Eurasian Spoonbill!! So if you twitch AOU rarities, send me a note and =
I
can tell you where it is! This is the 2nd or third record for the New =
World
I think.=20
=20
The Snowy and Little egret situation has grown more difficult for me, =
the
more I look. Up until this year, it seemed really easy, but a couple of
things changed. One was that we visited Barbados this time. There we saw
plenty of Little Egrets. The other situation was that in Antigua where I
have seen them before, this year there were more than ever (at least 7) =
and
one seen at an egret breeding colony. So they are likely breeding in =
Antigua
as well as Barbados. Our tour was a little earlier this year, and we =
noted
that basically all the Little Egrets in Antigua had yellow lores. This =
is
not too troubling as it is expected during the height of the breeding
period. What was troubling was seeing 2-3 different birds which had a =
plume
pattern intermediate between Little and Snowy; they had longer plumes =
but
mixed with shorter =93fuzzier=94 ones. The long plumes were not two =
single,
discrete plumes, but shaggier looking long plumes. It suggests that at =
least
in Antigua there is some hybridization; as it may be a new breeding =
locality
perhaps this is not unusual or unexpected. In Barbados they apparently =
do
not interbreed, and that breeding colony is well watched.=20
=20
My questions are: 1) Can Snowy Egrets ever show long plumes mixed in =
with
their shaggier crown plumes. 2) Are there any confirmed records of Snowy =
x
Little hybrids? 3) Would folks who see Little Egrets in the Old world be
uncomfortable with yellow lores at this time of year, on birds with well
formed double plumes?=20

Subject: Re: Little Egrets, Snowies and spoonbill.
From: Floyd Hayes <floyd_hayes(AT)YAHOO.COM>
Date: 22 Apr 2008 8:59am
There has been at least one direct observation of
mating between Little and Snowy Egrets in Barbados. I
quote from the Southeastern Caribbean Bird Alert
1999-15 (which I wrote):
"During five years of observing the breeding LITTLE
and SNOWY EGRETS at Graeme Hall Swamp, there was no
evidence of mixed pairs until a LITTLE EGRET was seen
courting with and then copulating with a SNOWY EGRET
on a nest in early April; the same SNOWY EGRET was
then seen copulating with a male SNOWY EGRET!"
I'm not sure whether it was observed by Martin Frost
or Eddie Massiah (the two local Bajan birders) or Mark
Gawn, a Canadian birder who was living there at the
time.

(Sorry, I had somehow overlooked this up to now, hence the very late
reply.) I think we do have a definite ID issue here.
The pics I have seen all show only the first bird:

http://www.pbase.com/james_lowen/image/93707390
...so this is the only one about which I can write something meaningful.
This bird certainly looks very much like what I would expect of an
Elegant Tern in, say, August or September. But in late February...?
The bird's head seems mostly black (with black extending down to bill
base on the forehead - this is not a winter-plumaged head), and some
white creeping out above the eye and on the lores, "pepper-and-salt"
fashion. The outer hand (p6-10) is decidedly worn; there is a molt limit
between p5 and p6 but no active molt there; p1(-2?) are in the process
of being replaced. The tail is clearly in active molt as well, with
inner feathers new, outer feathers still old, and intermediate lacking.
This is fully consistent with a bird starting a post-breeding complete
molt. Head is going out of summer plumage. The 5 outer primaries are
almost one-year-old; p3-5 have been replaced during the previous partial
pre-breeding molt; the complete wing replacement is starting in the
inner hand. Tail feathers are replaced only during complete molts.
This is a late summer bird, not a late winter bird - a bird on a
southern hemisphere schedule.
This is also exactly the state of plumage I would expect at this time of
the year for a Cayenne from the southernmost populations. These are the
longest-billed among Cayennes, and they can certainly also have a bill
with this type of Elegant-like color pattern.
What makes this something else?
Cheers,
Laurent -

Hi Laurent,
This is fascinating ...
If this bird is a "Southern" Cayenne Tern, with such a large, long and
bicolored bill, flat gonydeal angle and a strongly decurved upper mandibule,
blackish-red legs and a long shaggy crest (down to the shoulders), isn't it
a geographical variation that deserves subspecific status recognition ?
Or is it just clinal ? I haven't seen many illustrations/photos of those
yet.
???
