Bird of prey
Falcons are small to medium-sized birds of prey with long pointed wings. Unlike most other raptors, they belong to the Falconidae rather than the Accipitridae. Many are particularly swift flyers. Instead of building their own nests, falcons appropriate old nests of other birds, but sometimes they lay their eggs on cliff ledges or in tree hollows. Kestrels are the smallest birds in the group. Caracaras are a subgroup of the Falconidae unique to the New World, and most common in the tropics.
