Capitalization of bird names

Deborah Hecht <hechtlich@...>

I have no idea about birds, but in all other things zoological, only
scientific names are capitalized, and then, only the genus. Species is in
lower case. With common names, there is no need for capitalization except
if the common name contains somebody's name; in that case, the somebody's
name is capitalized, as in Townsend's warbler. Otherwise, I would think
it's just stylistic.
