Sakhalin Leaf Warbler

Gangly duck with long neck and legs. Unmistakable adult has chestnut-and-black body with electric pink legs and bill. Look for the bold white wing stripe, especially visible in flight. Juvenile is duller brownish overall with gray bill and legs. Young birds could be confused with Fulvous Whistling-Duck, but juvenile Black-bellied has a white wing stripe and typically shows some black coming in on the sides and belly. Flocks gather in marshes, lakes, rice fields, and swamps, sometimes by the hundreds. Active day and night. Occurs throughout Middle and South America. Range is expanding northward in the U.S., but still largely restricted to southern states. Vocal and conspicuous; listen for wheezy whistles and chirps.

Well-named, plain gray with black wings and dark mask. Iridescent blue-purple shoulder is usually not visible. Most similar to Palm Tanager but grayer (not olive) without pale patch at base of primaries. Also could be confused with Blue-gray Tanager in poor light, but Plain-colored's dark wings are more contrasting. Sexes alike. Seen in pairs or small flocks in open woody habitats like forest edges or shrubby second growth.

Tiny bird, plump and active. Most obvious features are pale eyes and rufous crown with black spots (rarely raised to a crest). Even when crest not raised, crown often looks shaggy. Combination of size and crown pattern helps separate from other small flycatchers. Otherwise nondescript: overall olive-brownish, whitish belly with blurry streaking, subtly paler wingbars. Found singly or in pairs along forest edge, second growth, or sometimes inside forest. Makes pipping notes and a short insectlike trill.
