Black-throated Gray
Warblers while fairly
common in San Francisco
during their short migrations
to and from Mexico are
quite uncommon during
winter here.
The lack of a black throat
(adult male) or a black
band at base of throat
(adult female) indicate this
bird is a first winter female.
Certainly one of our most
beautiful winter birds, the
very dark auriculars of this
Townsend's Warbler,
identifies it is an adult male.
One of the more variable
warblers in winter plumage,
the yellow throat on this
Yellow-rumped Warbler
indicates it is of the
"Audubon's" variety.
There were also a good
number of "Myrtle's"
Yellow-rumps on hand, by
our estimate about 10% of
the 100 or so we looked at.
The celebrity by virtue of
it's rarity anytime of year in
SF was this Worm-eating
Warbler.
A ground nesting warbler of
the Southeastern U.S. it
winters in Southern Mexico,
The Carribean and Central
America so this is one bird
that is very lost or a true
pioneer of it's species.
