List of Falconidae : ウィキペディア英語版 | List of Falconidae
Falconidae is a family of diurnal birds of prey and includes caracaras, laughing falcon, forest falcons, falconets, pygmy falcons, falcons and kestrels. They are small to medium-sized birds of prey, ranging in size from the black-thighed falconet, which can weight as little as , to the gyrfalcon, which can weigh as much as . They have strongly hooked bills, sharply curved talons and excellent eyesight. The plumage is usually composed of browns, whites, chestnut, black and grey, often with barring of patterning. There is little difference in the plumage of males and females, although a few species have some sexual dimorphism in boldness of plumage. They differ from other Falconiformes in killing with their beaks instead of their talons. They have a "tooth" on the side of their beak for the purpose. They are classified in eleven genera and 67 species of which two are extinct. ==Caracaras== Caracaras are principally birds of South and Central America. They are classified in five genera and 11 species of which one is extinct since 1906. Unlike the ''Falco'' falcons in the same family, the birds in the five relevant genera are not fast-flying aerial hunters, but are comparatively slow and are often scavengers (a notable exception being the red-throated caracara).
