Upland Buzzard

Buteo hemilasius

The upland buzzard (Buteo hemilasius) is a species of bird of prey in the family Accipitridae. The largest species of the Buteo genus, this buzzard lives in mountainous grassy and rocky areas in areas of Central Asia, northern South Asia and East Asia from Kazakhstan to Korea. The upland buzzard is migratory but typically covers a short distance apparently to avoid snow cover that may hamper prey capture. This species primarily subsists on small mammals but does not shun alternate prey from small to large birds and insects. This little known raptor has a large range, and though generally uncommon, it is not thought to be rare or declining as a species. As a result it is classified as least concern by the IUCN. The total length of the upland buzzard is 57 to 72 cm and wingspan is 143 to 161 cm. The Upland buzzard is conspicuously large for a Buteo, with long wings and a relatively long tail, and fairly eagle-like compared to related species. There are both pale and dark morphs. The pale morph is generally beige and earthen dark brown in colour. This morph bears a lightly marked whitish colour with a variable ochre wash to the head and nape with the chest generally appearing purest whitish. On pale morphs, the whitish chest is contrasted with dark brown areas widely but irregularly distributed across the lower breast and abdomen. The flanks and belly are similarly dark, while the tail is greyish with dark sides and prominently dark bands, with a heavier sub-terminal band. The coverts on perched buzzards can appear lighter brown than elsewhere. In flight on pale morphs, the major coverts are variable, appearing somewhat streaky brown, contrasted with a very strong blackish patagium mark. The flight feathers appear whitish with a variable amount of dark barring leading into the blackish wingtips and trailing edges. Dark morph upland buzzards are almost entirely solid black-brown throughout the body. with the flight feather pattern similar to pale morph but darker apart from the flight feathers. The call of the upland buzzard is a prolonged nasal mewing, not dissimilar to that of the common buzzard (B. buteo), although it is said to vocalize less than that species. The "trousers" are heavily feathered brown, often covering at least three-quarters of the legs. Despite individual variations, these buzzards are more insulated on their legs than other Buteo, apart from the ferruginous hawk and rough-legged buzzards (B. lagopus) which both have feathering extending along their tarsi.
