Medium-sized greenish bird with a bright yellow underside and black head. Occurs in a variety of habitats, wherever there are trees, including forest, open woodlands, and gardens, in the lowlands and foothills. Usually encountered in pairs or small groups. Yellow throat and lack of black in the wing separates this species from Black-hooded Oriole. Unmarked, black head identifies Black-capped Bulbul from Yellow-eared and Yellow-browed Bulbuls. Song is series of warbling whistles, rising at the end, “wet-wet-wet-wer-wer-wer-weer.” Also gives churring calls.
