Usually found in small family groups of three to six individuals (2), the straw-headed bulbul feeds primarily on berries and other fruit, including mistletoe berries, figs and wild cherries (2). Bulbuls generally swallow fruits whole, passing out the seeds intact, and are therefore often considered to be important dispersers of seeds in the forests in which they occur (7). In addition to this frugivorous diet, the straw-headed bulbul also feeds on small invertebrates such as small river-dwelling snails, spiders, beetles, bees and cockroaches, and has even been known to prey on flying lizards (Draco species) (2). It often feeds on the ground, uttering low gurgles or harsh chattering as it moves about searching for food (2) (4), although the straw-headed bulbul is also capable of catching some flies and beetles while in flight (2).
The straw-headed bulbul breeds between January and September. It constructs a fairly large, shallow nest from thin twigs, rootlets, grass and plant fibres in the branch of a small tree, a few metres off the ground, and typically lays a clutch of two eggs (2). The eggs and chicks are attended to by both parents, and there is some evidence that other members of the group also assist with the raising of the young (2).
