Thanks, Bill.
Your reference kind of supports my interpretation, that sometimes the =
young males look like females except for the one male plumage =
characteristic I've been noticing. Peterson's "Warblers" shows a young =
male that looks a lot like the adult male while "Warblers of the =
Americas" shows a bird more like you've described below. The part of =
the wing I've been seeing white is called the alula and makes up the =
feathers at the wrist of the wing (see Peterson's Warblers). "Warblers =
of the Americas" shows a plate of a young male almost like I've been =
seeing, except the alula and the primary coverts are brighter white in =
these few birds I've seen (four this fall).
I guess I've answered this question for my self. These must be the =
young males. This is confusing. Compare the plates of young =
Black-throated Blue in a"Warblers" and "Warblers of the Americas". They =
look nothing alike.
Good Birding,

Peter Pyle's book "indentification guide to North American Birds"
states "AGE/SEX- Juv (Jun-Aug) is like HY/SY ,but the plumage is =
heavily
washed with brownish; juv female =3Dmale, although the distinctive
sex-specific plumage of male is often visible before fledging.. =
Basically if
I understand the jargon correctly he is saying that in many cases the =
male
is distinguishable before fledging but not always in which case males =
are
heavily washed brownish. I quoted the book excactly because I don't =
totally
trust my interpretation.

"Warblers of
