Scientific Name: Buteo japonicus

Malay Name: Helang-Gempal Biasa

Chinese Name: 普通鵟

Range: Breeds in eastern Siberia through Sakhalin to Hokkaido, winters south to continental southeast Asia. Resident in Japan with endemic taxa in the Izu and Bonin islands, as well as the Daito Islands.

Taxonomy: Polytypic. Subspecies are: burmanicus, japonicus, toyoshimai, oshiroi.

Size: 51-57 cm

Identification: Buteo buzzards have a roundish body and in flight, is disitnct with roung wings and a proportionally short tail. In Singapore very difficult to distinguish from the Common Buzzard, but Buteo buzzards with primarily white base colour on the underparts with strongly contrasting black carpal patch are thought to be of this species.

Similar looking species: Crested Honey Buzzard, Jerdon's Baza, Changeable Hawk-Eagle, Common Buzzard

Habitat: Open country.

Behaviour/Ecology: Taxonomy of the Buteo buzzards very confused, with various authors treating this and the Common Buzzard differently. Usually found in open country, though not very frequently observed wintering in Singapore. When hunting, it has a habit of soaring against the wind and staying completely stationary in the air, looking downwards to search for its prey. This behaviour however is almost never observed in Singapore due to the lack of suitable habitats.

Local Status: Rare migrant

Conservation Status: Least Concern (BirdLife International 2021)

Location: Observed migrating across key raptor watch sites. Sometimes winter at open country sites such as Holland Plains, Marina East.
