One of numerous species and genera of rapacious birds of the family Falconidæ. They differ from the true falcons in lacking the prominent tooth and notch of the bill, and in having shorter and less pointed wings. Many are of large size and grade into the eagles. Some, as the goshawk, were formerly trained like falcons. In a more general sense the word is not infrequently applied, also, to true falcons, as the sparrow hawk, pigeon hawk, duck hawk, and prairie hawk.
To catch, or attempt to catch, birds by means of hawks trained for the purpose, and let loose on the prey; to practice falconry.
