[11] They are incredibly fast fliers, with the Peregrine falcons having been recorded diving at speeds of 320 km/h (200 mph), making them the fastest-moving creatures on Earth ...

Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, [4] ornithologists typically use the narrower definition followed in this page, [5] excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily ...
The lanner falcon (Falco biarmicus) is a medium-sized bird of prey that breeds in Africa, southeast Europe and just into Asia. It prefers open habitat and is mainly resident, but some birds disperse more widely after the breeding season. A large falcon, it preys on birds and bats. [2]
Crested caracara, Brazoria National Wildlife Refuge Crested caracara (C. plancus) in flight Caracaras are birds of prey in the family Falconidae.They are traditionally placed in subfamily Polyborinae with the forest falcons, [1] but are sometimes considered to constitute their own subfamily, Caracarinae, [2] or classified as members of the true falcon subfamily, Falconinae. [3]
