Common Kestrel
チョウゲンボウ
Scientific name: Falco tinnunculus
The Common Kestrel is a small falcon often seen hovering over fields, riverbanks, grasslands, and open countryside. In Japanese it is called チョウゲンボウ / Chōgenbō. It has pointed wings, a long tail, sharp eyes, and a quick, light flight style.
The male has a gray head and tail, reddish-brown back with dark spots, and pale underparts with fine markings. The female is browner overall, with barred wings and tail. Both sexes often hover in one place while searching the ground for prey — one of the best ways to identify this species in the field.
In Japan, the Common Kestrel is found in open habitats, especially farmland, riverbanks, grasslands, reclaimed land, coastal fields, and urban edges with open hunting space. It may also nest on cliffs, buildings, bridges, towers, or other high structures.
Habitat: Farmland, grassland, riverbanks, open fields, coastal plains, urban edges
Range in Japan: Widespread in suitable open habitats; local and patchy depending on region
Diet: Small mammals, insects, small birds, reptiles, and other small animals
Season: Year-round in some areas; winter visitor or seasonal mover in others
Size: About 33–38 cm
Nesting: Uses cliffs, building ledges, bridges, towers, or old nests; does not build a large nest itself
Behavior: Famous for hovering in the air while hunting; dives down quickly when prey is found
Conservation: Common in suitable habitat, but open farmland, grassland, and safe nesting places are important
