Mangrove Gerygone

Small songbird, dull brownish-olive above, pale below, with prominent white supercilium, black eyeline, and faint, narrow wingbars. Vertical tail pumping distinguishes this species from most others in its range except Sakhalin Leaf Warbler. Favors the lower stories of vegetation more than most other leaf warblers, often descending down to the ground while foraging. A high-pitched cricket-like trill of a song distinguishes this species from the nearly identical Sakhalin on migration (no overlap in breeding range). Calls of the two species are similar, and can only be differentiated reliably using a spectrogram; Pale-legged’s call is marginally higher in frequency. Breeds in sparsely wooded areas, particularly in valleys and hills; can be seen in a wide range of wooded habitats outside of breeding period.

A medium-sized bird of lowland forest on Bohol, Leyte, and Samar islands. Has a pale blue bill and deeper blue eye wattle, a black face, a streaked crown, a reddish-brown back, a dark wing with a pinkish to white wingbar, a thin white collar with some scaling above, and a reddish rump and tail. Underparts are white in the female and pinkish in the male. Makes short sallies for insects. Can be found in pairs, small groups, or sometimes mixed-species flocks. Unmistakable. Voice includes a plaintive whistle and a sharp “tyik!”

Large, boldly-marked thrush of high-altitude open meadows, steppelands, and gardens in central China. Male is dashingly colored with an ivory-white back and breast, a brick-orange belly, and jet-black wings and head. Female is dirt-brown overall with darker wings and a hint of the male’s pale back and breast. Similar to Chestnut Thrush, but Chestnut Thrush prefers more forested habitats and lacks pale patches on the body.
