Blue-gray gnatcatcher (Polioptila caerulea)—Karl H. Maslowski
Any of about 15 species of small songbirds (genus Polioptila, family Polioptilidae). The blue-gray gnatcatcher, 4.5 in. (11 cm) long, with its long white-edged tail, looks like a tiny mockingbird. It breeds locally from eastern Canada and California to The Bahamas and Guatemala and winters from the southern U.S. southward. The black-tailed gnatcatcher lives in the deserts of the southwestern U.S.; the other species are found in Central and South America and Cuba.
