Accipitriformes

Accipitriformes is an order of mostly diurnal birds of prey, including hawks, eagles, kites, harriers, and Old World vultures. Its members generally have hooked bills and strong feet adapted to capturing or feeding on animals.

Accipitridae: A large family of birds of prey that includes hawks, eagles, kites, harriers, and Old World vultures. This family contains most living species traditionally placed in Accipitriformes.
Golden eagle: A large Northern Hemisphere eagle that hunts mammals and birds. It exemplifies the powerful aerial predator among accipitriforms.
Accipitriformes fossil record: Fossil evidence documenting the evolutionary history of accipitriform birds. Fossils help trace when major lineages of the order appeared and diversified.
Trophic cascade: An ecological sequence in which changes at one trophic level affect other levels. Predators such as eagles can alter prey populations and the species those prey affect.
Sagittariidae: The family containing the secretarybird, a long-legged African bird of prey. The secretarybird represents a distinctive family within the order.
Peregrine falcon: A widespread falcon known for high-speed hunting dives. Its raptor lifestyle resembles that of accipitriforms, but falcons belong to another order.
Bird classification: The scientific organization of birds into nested taxonomic groups. Accipitriformes is a rank in the changing classification of birds.
Vulture decline: The reduction of vulture populations caused by threats including poisoning and habitat loss. Declines among Old World vultures disrupt scavenging services provided by accipitriforms.
Cathartiformes: An order of New World vultures, including condors and turkey vultures. New World vultures resemble Old World vultures but belong to a separate order in many classifications.
Osprey: A fish-eating bird of prey and the sole living member of family Pandionidae. Its classification near or within Accipitriformes has varied among taxonomic systems.
