One more observation on this bird. The pattern of lighter yellow appears
different on each side of the head with the prominent line behind the eye
only clearly visible on the left side and more yellow visible in the cheek
on the left side. These differing patterns appear consistent between
different pics.

Hi all,
Quite the interesting bird, an incongruous Mr. Potatohead bird with
features stuck randomly together all signifying ..? I'm inclined to think
there is some sort of hybridization at play here. I think the bill looks,
long-ish and very pointy, is good for Orange-crowned as is the dull
streaking on the underparts, the little whitish patch between the legs,
and the color of the undertail coverts the proportion to their tail
retrices and the *seeming *dark undertail (that first picture seemed to
show whitish undertail and Tye has mentioned white flashes seen in the
tail). The leg color of normal-pigmented OC is darkish and this bird's is
pinkish-organge-ish...
For Hooded Warbler, the bill seems wrong--they have an all around more
hefty, black and dull-at-the-tip bill. The cheek pattern seems somewhat
suggestive of this species and *if *the undertail is indeed white
then....hmmm.
I agree with Jeff. G that the bill seems wrong for a pure Wilson's ---too
long and pointy. The crown, though, looks pretty good and the color of the
legs is in range of Wilson's. Then again, the plumage on the belly/lower
breast doesn't seem good for pure Wilson's either.
So, I think you put some different-species-of-warbler genes (those 3
sp.) in a pot and stir. Thanks for sharing, Tye.
good birding and puzzling all, Tom

Hi -
At this point I think both pigment-challenged Orange-crowned and
Orange-crowned X Wilson's seem to be viable possibilities.
To address your comment Phil,
"I'm not sure any hybrid combo can explain that leg and foot color."
Most commonly, hybrid birds show plumage characters intermediate between
their parents, and/or a mix of parental characters. However, it is not
that rare to see hybriids that show features not present in either parent.
This is particularly well-known in waterfowl, but also has been seen in
other groups. The illustrations in Reeber's "Waterfowl of North America,
Europe, and Asia" show quite a few of these.
Among dabbling ducks, lots of hybrids show a green patch around the eye
like an American Wigeon (e.g. some Brewer's Ducks [Gadwall X Mallard],
Shoveler X Gadwall, Pintail X Gadwall). Others have face patterns
resembling Baikal Teal (e.g. N. Pintail X Eurasian [Common] Teal,
Green-winged Teal X Blue-winged Teal).
The best explanation I have seen is that these are ancestral patterns,
and the modern species still have the genetic coding for them, but it has
been suppressed or masked, and in the hybrids the masking or suppression is
disrupted.
So back to leg and foot color: Hybrids could easily have the genetic
control of soft-parts pigment disrupted.

Colby Neuman is not on obol but suggested this might be an
orange-crowned warbler with pigment issues. The more pics I see the more I
agree that the strange head pattern on this bird is a result of a patchy
pigmentation deficiency of some sort. Might explain thos bright orange
legs too.
