Tom Olson and Carrie Burkholder sent me some photos (attached) of an
unusual Fox Sparrow who has been visiting their feeder recently.
It appears to belong to the "Red Fox Sparrow" group, which consists
of two subspecies. Both subspecies typically winter from Texas to
the Atlantic coast, and are notably rare in the West.
I've seen a few photos of our typical wintering "Sooty Fox Sparrows"
with unusually reddish plumage (like
this
one, from
this
article). But, these unusually red individuals don't seem to
have the distinctive facial pattern of the "Red" group. I don't
know too much about eastern Fox Sparrows and find some of the
distinctions to be fairly subtle when these individual variations
come into play.
I also attached a picture of a "Sooty" Fox Sparrow for comparison.
This one's a little redder than many of them. Many are even more
uniformly chocolate brown, with a reddish-brown rump and tail.
