Dusky-chested Flycatcher

A medium-sized black tern with a tail that appears square or slightly forked. Smaller and darker than Brown Noddy with a shorter tail, thinner bill, and more contrasting white cap. Uniformly black back, wings and tail, and dark legs, except on the main Hawaiian islands where tail and rump are grayish and feet and legs are bright orange. Nests on coastal cliffs, in sea caves, and in trees. More often seen in groups than Brown Noddy. Often seen from shore.

Small songbird, essentially identical in plumage to Arctic Warbler and Japanese Leaf Warbler. A late spring migrant, often moving up the Chinese coast from Southeast Asia in mid- to late May. Breeds in the taiga forests and forest edges of the Kamchatka peninsula, Hokkaido, Sakhalin, and the Kuril Islands. Call is a low “chuck,” averaging lower than that of Japanese Leaf and Arctic Warblers. Song is a broken series of chattering notes, with each segment being in more discrete phrases than the more consistent, higher-pitched song of Arctic.

Small honeyeater of coastal heathland in southern Australia. Brownish above, pale below, with white brow, tan crown, and black cheeks that extend down onto the breast, ending in black stippling. Yellow in primaries and salmon underwing evident in flight. Juvenile brownish above, paler below, with yellow in wing. Call a mournful piping whistle, with some tones recalling Spiny-cheeked Honeyeater.
