Hook-billed Bulbul Setornis criniger

A highly localized species, found almost exclusively in the kerangas and peatswamp forests of Borneo and Sumatra’s lowlands (rarely in adjacent wooded habitats). Fairly plain overall; note brown upperparts, off-white chest, pale yellow belly, and elegant white eyebrow. Long and heavy hook-tipped silver bill is diagnostic if seen well. Forages singly, in pairs, and in small bands, typically in the middle and lower levels of forest. Gives a variety of harsh scolding calls, including a nasal “jyaw, jyaw” and a quicker, drier rattle.
