rough-legged buzzard; rough-legged hawk
A bird of prey (Buteo lagopus) found in northern regions. In Japanese, the katakana name ケアシノスリ is the usual form.
In Hokkaido, rough-legged buzzards can sometimes be seen in winter.
Kanji spelling used in specialized bird literature; the character 鵟 is uncommon.
The name ケアシノスリ literally means 'hairy-legged buzzard', from 毛 (ke, 'hair/fur'), 足 (ashi, 'leg/foot'), and ノスリ (nosuri, 'buzzard'). The exact derivation is uncertain, but it likely describes the feathered legs characteristic of this species.
