Black-and-white Warbler


The computer from which I blog is experiencing "The Blue Screen of Death." Here is a posting I never got around to last year.

Black-and-white Warblers are a common migrant in Northfield. In the fall, males and females can be tricky to tell apart. In these photos, the male’s underparts are bright white. The female is pale buffy below. Because they winter north to the Gulf and the southeast Atlantic Coasts, Black-and-whites are among our first warblers to appear in the spring. By that time, the males throats have become mostly black.
