Genus Species subspecies Region Range
Butastur liventer OR Southeast Asia, Java, also Sulawesi


Members of the genus Butastur are medium-sized hawks, with long and pointed wings, and a medium length tail. The bill is rather weak, the basal portion and cere being brightly coloured. The legs are relatively short and reticulate, with a row of larger scales down the front. The colour pattern is subdued, rufous brown, grey and whitish. The young are not very different from adults. Butastur is found in Africa and tropical Asia. The four species form a super-species; though there may be some overlap between two of them. One nests in Japan and north Asia, but is highly migratory.

Physical charateristics

The adult Rufous-winged Buzzard is 35?40 cm long. It has a grey head and underparts, with some streaking on the crown, neck and breast. The rest of the upperparts are rufous grey, and the uppertail is bright rufous. In flight, from above it shows rufous-chestnut flight feathers and the rufous uppertail, and from below it has a grey body, white underwing coverts, and greyish flight feathers and undertail. The juvenile is duller and browner, with a brown-grey head and white supercilium.

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be small, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
