Gansu Leaf Warbler

Common antwren of mixed-species flocks in forest canopy, but sometimes found away from them; heard frequently but seldom seen. From below, note clean white underparts, long tail, and rather heavy bill. Moves sluggishly along branches and examines leaf clusters. Often occurs in the same flocks as Spot-tailed Antwren and is not safely separable from that species under most viewing conditions, except by voice. Song is distinctive and given throughout the day, often when other species are quiet.

Very small and generally uncommon jacana. Adults show rufous on the crown, breast sides, rump, and tail. Juveniles are duller. Most distinctive in flight, when the white trailing edge to the wing is revealed. Found in thickly vegetated wetlands, especially those with waterlilies. Seems to move around in response to changing water levels. Call is a quick, hooting series. Often confused with immature African Jacana, but smaller and with a shorter bill that never shows any blue. Easily separated in flight by the white stripe at the back of the wing and the pale patches on top of the wing.

Breeding males are striking and unmistakable: especially look for white wing patch, head pattern, and thick black streaks on underparts. Females and immatures are less obvious and might be mistaken for Canada Warbler, but combination of gray head, yellow underparts, white wingbars, and at least some dark streaks on the flanks is distinctive. Always look for tail pattern from below: basal half is white, tip is black. Breeds in coniferous forests, especially with dense understory. Migrants and wintering birds can be found in any wooded area or edge. Winters primarily in Central America and the Caribbean.
