the common name for birds of the subfamily Daptriinae, family Falconidae, order of diurnal birds of prey. In contrast to the true falcon, the caracara lacks a tooth on the upper beak and has naked cheeks and throat (sometimes sparsely covered with feathers). It has blunt wings, a long crop, and weak claws. It flies rather poorly but runs well; therefore it tends to stay on the ground.
