What is the fastest bird in the world?
The Peregrine falcon (Falco peregrinus), also known as the peregrine, is a widespread carnivorous bird in the family Falconidae. The peregrine looks like a crow-sized falcon of a blue-grey color with barred white underpants, yellow feet, black head and small sharp peak.
As many birds of prey, peregrines are sexually dimorphic, and their females are different from males, as females are usually larger in size. Peregrines' speed is the main distinguishing feature of the species, as it can reach 322 km/h (200 mph) when a peregrine is diving for its prey. This makes the peregrine the fastest member of the animal kingdom.
