In common with the European honey-buzzard, the Oriental honey-buzzard feeds predominately on the combs, larvae, pupae and adults of social bees, wasps and hornets, but will also take other insects, reptiles, frogs, small mammals, and young or injured birds (3) (5). It is normally a solitary and secretive bird, but sometimes aggregates in small flocks when migrating or moving locally in response to food supplies (3) (4). Breeding occurs during the summer in close association with fluctuations in the abundance of food (3). During courtship, aerial displays are common and typically involve solitary and mutual circling, and distinctive undulating rollercoaster-like flight. The nests measure up to 80 centimetres across and are usually made from twigs and leaves, and positioned at heights of 6 to 28 metres in a tree (3) (5). The female lays, on average, two eggs, which are incubated for between 28 and 35 days. After hatching both the male and female participate in feeding the young (5), which fledge after around five to six weeks and become independent after another five to eight weeks (3).
