Sooty-headed Bulbul Pycnonotus aurigaster

A dark-headed brown bulbul with a bright red vent; common in towns, plantations, and forest edges. Red-vented Bulbul, with which it overlaps in southwestern China, can be similar, but it has a completely black head. Juvenile has orange vent and can be confused with Brown-breasted Bulbul, but the latter has a more strongly peaked head, no white tail trimming, brown auriculars, and a more contrasting white throat. Often seen in pairs and small flocks, foraging at mid-level and on the ground. Song consists of high-pitched warbling calls.
