ヒメチョウゲンボウ Falco naumanni

Elegant little falcon, often seen in groups. Males are unspotted above with a blue-gray head and similarly-colored patches on the upperwings; also note largely pale underwings. Females have an indistinct moustache and slightly paler cheek, but are otherwise very similar to Eurasian Kestrel. Shape very similar to Eurasian Kestrel but tail slightly shorter and central tail feathers can project slightly. Wings are more rounded and shorter than those of Eurasian Kestrel. Hovers frequently and catches insects on the wing over open terrain. Breeds in noisy colonies on buildings and cliffs.
