The Accipitres (Accipitridae) are the birds of prey order of the Aves (birds) class of animals. They are characterised by a strong, crooked beak with an acute, downward curving point with sharp edges. The base of the beak is enveloped in a naked skin (the cere) in which the nostrils are placed. The feet are muscular. The toes are armed with powerful talons, long, curved and pointed, of which those of the hind and innermost toes are the strongest. The wings are adapted for vigorous, lofty and long-sustained flight. Research Accipitres
Falconidae is the Falcon family of the Accipitres order of birds of prey. The beak is hooked and generally furnished with a sharp projection or tooth on each side. The head is wholly covered with feathers apart from the cere. The feet are strong and armed with curved, retractile, sharp talons.

Strigidae is the Owl family of the Accipitres order of birds. They are characterised by a large, feathered head with large eyes, dilated and projecting, each surrounded by a concave disk formed of stiff diverging feathers, concealing the cere and nostrils. The ears are large and of elaborate construction. The plumage is lax and downy, adapted for slow and quiet flight. Research Strigidae
The Vulturidae are the vulture family of the Accipitres order of birds. They are characterised by a somewhat lengthened beak with a nearly straight upper mandible, curved at the point only. The head and neck are naked to a greater or lesser degree or covered only in a thin down. The talons are comparatively weak and the family feeds exclusively on the flesh of already dead animals.
