Falcons are fastest birds, with the Peregrine Falcon being the fastest animal in the world. The term falcon comes from the latin work 'falco' meaning scimitar-shaped. This refers to the long narrow shape of their wings. The wings which are swept back from their body enables their speed. Most Falcons also have a notch in their upper beak.
