Black-and-White Warbler, Mniotilta varia


Black-and-White Warbler
Black-and-White Warbler is an eastern species, found irregularly in fall and winter in the Bay Area. The one shown above was seen by many local birders in Christmas season 2006 in the sycamores along Penetencia Creek in eastern San Jose. It is a first-winter male, which closely resembles a female in breeding plumage -- no black on the breast, heavy streaking on the sides. The bird below, seen near Lake Merced in San Francisco during Fall 2012, is a non-breeding-plumage female, showing indistinct streaks on the flanks and behind the eye.
