Buru Green-Pigeon

Uncommon in humid evergreen forest of tropical lowlands, where lives mainly at middle to upper levels in forest canopy. Presence often revealed by loud whistled “PEE-HAH” calls, which can be given in response to loud noises such as a sharp handclap. Often perches still and rather upright for long periods, sallying out occasionally for fruit and small invertebrates. Plumage bright rusty overall, with paler eyering and slightly bushy face. Rufous Mourner looks very similar but smaller and sleeker.

Large, long-tailed antbird. Males are gray, paler below, with a black bib. Females have a chestnut cap and white throat. Occurs in the understory of hillside deciduous forests that are rich in bromeliads and lianas. Both sexes sing a series of “peer” notes.

Small plump leaf warbler. A “Pallas’s-type” leaf warbler: stout, with a pale rump, crown stripe, and prominent brow stripes. Olive-yellow above with a faint gray wash on the nape. Chinese is distinguished from Pallas’s by its paler, more faded-looking brow and crown stripes, less yellow suffusion all over the body, less compact appearance, and less obvious or absent upper wingbar. Extremely similar Gansu Leaf Warbler and Lemon-rumped Warbler can be difficult to separate; note Chinese’s slightly more elongated and less rounded appearance, a lack of a distinct hook under the end of the brow stripe, less contrasting and more yellowish head patterning, and paler yellowish secondaries. Forages actively, often hovering and hopping about at mid-level. Breeds in montane broadleaved deciduous or mixed forest; moves to lower elevations in winter. On average, found at lower altitudes than Lemon-rumped and Gansu. Lengthy song is unique and bizarre, with a twanging, grating quality: “btrichi-btrichi-btrichi.” Call is an explosive “wip!”, often repeated in medium-length series on the breeding grounds.
