Obi Golden-Bulbul Hypsipetes lucasi

A thrush-sized bird with a heavy bill, olive-green upperparts, and a yellow underside. Particularly note the yellow cheeks and the yellowish patch beside the bill, making the dark eye stand out from the face. Pairs and small groups inhabit forests, edges, scrubland, and plantations. Confined to the island of Obi. Separated from female Black-chinned Whistler by unscaled throat, solid yellow underside, and yellow facial sides. Vocalizations include an inflected high-pitched whistle, “tseeooeee.” Also gives a staccato, two-note “wit-cheer” with a longer second note, plus nasal “too-too” calls.
