Description ADULT MALE Has mostly black plumage; red shoulder patch has bright white border. In winter, black feathers have gray-buff edges. IMMATURE AND ADULT FEMALE Dark gray-brown with heavy streaking on back and underparts; plumage is least dark on throat, malar stripe, and supercilium. IMMATURE MALE Similar to winter male, but buff feather edges are more obvious.


Dimensions Length: 7 1/2-9" (19-23 cm)


Habitat Wetland and farmland resident, almost entirely restricted to California.


Observation Tips Easy to see within range.


Range California, Southwest, Northwest


Voice Song is harsh, grating and screechy; call is a dull chuk.


Discussion Flock-forming, colonial bird. Bill is more slender than Red-winged's. Male is separated from typical form of Red-winged Blackbird by bright white (not yellow) edge to red "shoulder." Female is very similar to female Red-winged; some birds may not be identifiable with certainty in the field, but plumage is usually darker overall, without "warm" brown tones; throat is always whitish (some Red-winged females have a pinkish buff throat). Sexes are dissimilar.
