1. Accipitriformes (Buzzards, Eagles, Harriers, Hawks, Kites, and Old World Vultures)

Accipitriformes have strong legs and feet with raptorial claws and an opposable hind claw. Almost all Accipitriformes are carnivorous, hunting by sight during the day or at twilight. They are exceptionally long-lived, and most have low reproductive rates. The sexes have conspicuously different sizes and sometimes a female is more than twice as heavy as her mate.

The osprey, sometimes known as the fish eagle, sea hawk, river hawk, or fish hawk, is a diurnal, fish-eating bird of prey. It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply.

The secretarybird or secretary bird (Sagittarius serpentarius) is a very large, mostly terrestrial bird of prey. Endemic to Africa, it is usually found in the open grasslands and savannah of the sub-Saharan region. The generic name "Sagittarius" is Latin for "archer," perhaps likening the secretarybird's "quills" to a quiver of arrows.
