Lesser Racket-tailed Drongo

A small dull-colored warbler with a greenish upperside, instinct wingbars, a pale throat, and yellowish underparts. Singles, pairs, and small groups inhabit lowland and hill forest, including secondary forest. Often joins mixed-species flocks. Sings a variable high-pitched warble mixed with twittering phrases. The most similar species in its limited range is Biak White-eye, but Biak Leaf Warbler is identified by its more uniformly yellowish underparts. Separated from other small yellowish birds such as flowerpeckers and sunbirds by the shape of the bill.

Small and slim with a thick, pale eyebrow, a dark crown with a pale central crown stripe, and a heavily striped back reminiscent of the patterning of a snipe. Often perches acrobatically, gripping two stems at once. Breeds in open wet marshlands with scattered bushes or trees, often in areas with sedges; uses reed beds on migration; winters in West Africa, where it uses extensive shallow marshes. Song is fast and chattering. Rare across much of range; population is declining fast due to habitat loss.

A medium-sized blackbird with a short bill. Both sexes are similar; mostly olive-brown with rusty wings. Inhabits open woodlands, savanna, and scrubby areas, but also found in farmlands, plantations, and urban parks where is often seen in small groups. Uncommon in the Atlantic Forest region. The song includes melodical whistles with short buzzy notes; song varies among individuals.
