[Tweeters] Mystery Warbler and question for Collin

Tweets-

While American Redstart is of course a
possibility as a parent of this individual, I
want to point out that (obviously?) this plumage
combination (if it were a 2nd year full-blooded
American Redstart) is not commonly encountered,
even where Redstarts are very common. Looking for
"2nd year American Redstart" on google images
produces a few interesting photos, including this
one:

and

Searches for "1st year male" produced this:

Interesting is that these individuals show the
initial black starting at the EYES. Another point
is that 1st-year male American Redstarts often
have a pronounced orange cast to their spots. The
hybrid in the photos has TONS of yellow (way too
much yellow, even for a female redstart). And the
black streaks on the sides are not to be found in
any plumage of redstart. I think the BILL is also
a bit too long for an American Redstart. The
undertail pattern is also a bit off for American
Redstart.

In short, I think it's easy to eliminate this as
a full-blooded American Redstart. It's a lot
harder to figure out the actual parentage given
the oddities of genetics. I'll spend some time
with the warbler guide tonight. I'm still
thinking Oporornis by that bill shape. I'm not
even fully convinced that it's got Redstart in it.

Finally, a question for Collin- in one of the
photos, the bird has its mouth open... was it at
all singing? Please say yes.

Yours from Redstartland,
Jesse Ellis
