The Accipitridae are represented by one species of kite, 2 eagles and 10 "hawks." Hawk is a general name given to several predatory birds that are smaller than eagles. The only pandionid, the osprey, a fish-eating bird, breeds in Canada. They are most easily identified in flight by their long, pointed wings and rapid flight. The falcons are well represented in the Northern Hemisphere 5 species breed in Canada. The turkey vulture ( Cathartes aura) is the sole representative of the Cathartidae to breed as far north as Canada. All have keen day vision many are fierce predators, spotting small animal prey while in flight or perching and then swooping to kill. They are grouped into 5 families: the Cathartidae, comprising the 7 living New World vulture and condor species, all principally carrion feeders the Falconidae, 63 species including the caracaras, forest falcons and falcons the Sagittariidae, a single species of secretary bird ( Sagittarius serpentarius) the Pandionidae, a single species of osprey ( Pandion haliaetus) and the Accipitridae, 219 species of kites, eagles, Old World vultures and hawks.Īlthough many of the Falconiformes are superficially alike, each family is highly specialized and individuals vary widely in habitat requirements and food preferences.The birds range in size from the diminutive falconets, barely larger than sparrows, to the giant condors, with wingspans exceeding 3 m. This order includes over 300 species of mostly diurnal hunters.
