Rufous-winged Buzzard

The rufous-winged buzzard is a compact raptor 38–43 cm long. Adults have a grey head and underparts with fine streaking on the crown, neck and breast, while the mantle, flight feathers and tail are warm rufous-grey to chestnut. From below, the pale underwing coverts contrast with greyer flight feathers; from above, the bright rufous tail and wings are conspicuous. Juveniles are duller and browner with a pale eyebrow. Males and females are alike in plumage (Wikipedia, general species account, citing Robson).

A largely sedentary species of mainland Southeast Asia, Java and Sulawesi, it occupies deciduous forest, second growth and open wooded landscapes, generally below about 800 m. Birds spend long periods on exposed branches or poles, watching the ground before dropping onto lizards, small mammals and large insects. Its short, shrill call is often rendered as two notes. The combination of grey underparts and strongly rufous wings and tail distinguishes it from the migratory grey-faced buzzard where their ranges overlap (Robson, as summarised in Wikipedia's general species account).
