Forbes's Plover

Elegant seabird with extremely long wings and forked tail. Adults are pale gray with white cheek, black cap, and red bill and legs. Very similar to Common Tern; note shorter bill, shorter legs, gray belly, and paler gray wingtips with very limited dark tips. Young birds show partial black cap and black bill and legs; look for pale gray wingtips and stubbier legs to separate from Common Tern. Rarely seen away from breeding grounds on coastal islands or small ponds in the Arctic tundra. Migrates offshore, heading for wintering grounds in Southern Hemisphere.

Small songbird with bright yellowish upperparts and white “goggles.” Most subspecies have gray underparts; subspecies “unicus” of Sumbawa and Flores has a yellow belly. Compare with other white-eyes in various parts of their range; note present species combination of dark iris and yellow back. Inhabits a wide range of different wooded habitats across its range, including coastal scrub, mangroves, inland forests, and forest edge. Forages actively in small to medium-sized flocks, sometimes mixing with other species. Can be quite common on small islands. Twittering song is bright but unremarkable. Most frequently given call is a somewhat variable high-pitched, descending “djee.”

Nondescript warbler, generally olive-colored overall, but different populations vary from grayer to brighter yellow. Overall very plain and unmarked, but note short darkish line through eye and thin pale eye arcs. Forages for insects in scrubby areas, woodland edge, and thickets. Namesake orange crown is very difficult to see, and usually only a faint wash at best. More common in western North America, from Alaska to Mexico, where populations are brighter yellow-green. Birds in eastern North America are scarcer and drabber, often with a more contrasting grayish head. Bright yellow undertail coverts help separate Orange-crowned from the similarly drab Tennessee Warbler.
