Hawk

Hawk, a name often given to almost all the Falconidae, except the largest eagles, but also used in a more restricted sense to designate the Accipitrine section of the family, and for the most part referable either to the goshawks (Astur) or the sparrowhawks (Accipiter). Unlike the true falcons, they have an untoothed bill. The wings are short, somewhat rounded, and very concave beneath, and while the flight is rapid it is without much power of soaring or gliding.
