Californische muggenvanger Polioptila californica

Small, long-tailed songbird; similar to other gnatcatchers but darker gray overall. Male has black cap; female shows brownish tones to plumage. Underside of tail helpful in identification: almost entirely black with narrow white edges; much less white than both Black-tailed and Blue-gray Gnatcatchers. Very restricted range; found in shrubby sagebrush chaparral, usually in pairs. Listen for harsh scolding calls.
