Riverside Tyrant

A small, mostly yellow bird with a bold white eye-ring and a black head with a bright banana-yellow throat and underparts. Neck, back, and wings olive-green. Note black edges to wings and tail. Found in forest, forest edge, and open plantation or garden areas. Voice includes a tinkling song as well as “zching” and “sip sip” calls.

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.

A very small, warbler-like greenbul with an olive-green back, pale underparts, an olive-washed gray cap and nape, and a yellow or orange eye. Found in montane forest at middle elevations. Often joins mixed-species flocks. Very similar in appearance to Tiny Greenbul, but found at higher elevations and darker overall, with an olive-green wash to the crown and nape. Similar in overall coloration to Yellow-streaked Greenbul, but much smaller, with a pale eye. Voice apparently very similar to Tiny Greenbul’s. The call is a rough chattering trill that is often mixed with the song: an accelerating, syncopated series of low nasal notes.
