A falcon is any of several species of bird of the genus Falco, such as the peregrine falcon, which are raptors or birds of prey. These birds have thin, pointed wings which allow them to dive at extremely high speeds. Peregrine falcons, the fastest birds on earth, are said to have reached speeds of up to 200 mph. Other falcons include the Gyrfalcon and the Merlin. Some small insectivorous falcons with long, narrow wings are called hobbies, and some which hover as they hunt for small rodents are called kestrels. The falcons are part of the family Falconidae, which also includes the caracaras, laughing falcon, forest falcons, and falconets.
