Halmahera Golden-Bulbul Hypsipetes chloris

A thrush-sized bird with a fairly long horn-colored bill. Uniform rich olive-green above and all yellow underneath, with dark eyes. Juveniles duller and pale-eyed. Typically found in pairs or small groups in primary and degraded forest, plantations, and mangroves, in lowlands and lower hills. Confined to a cluster of islands in the North Moluccas where there are no other bulbuls or similar species. Loud, jumbled, characteristic bulbul-like-song consists of repeated “chidlydu-chidlydu-chidlydu” phrases. Also gives thin, high-pitched insect-like “tsee” notes and rasping “weerrrr” calls.
