Puff-throated Bulbul

The puff-throated bulbul is a large forest bulbul about 23 cm long. It has olive upperparts, yellow underparts and conspicuous loose white throat feathers that can be puffed outward. The feet are black and the iris and bill are brown. Males and females look alike. It resembles the white-throated bulbul but has duller yellow below, while its bulky shape and expandable throat patch distinguish it from smaller Pycnonotus bulbuls (MacKinnon, as cited by Wikipedia).

The species occurs from southern China through mainland Southeast Asia and usually remains in forest understorey. It lives in year-round territorial groups of two to seven and may breed cooperatively, although pairs can also nest without helpers. The female builds an open cup in low vegetation and alone incubates and broods; males and helpers assist by feeding nestlings and fledglings. Where more than one pair shares a territory, each uses a separate nest (Pierce et al. cooperative-breeding study; Sankamethawee et al. 2009).
