Adult falcons have thin tapered wings, which enable them to fly at high speed and to change direction rapidly. Fledgling falcons, in their first year of flying, have longer flight feathers which makes their configuration more like that of a general-purpose bird such as a broadwing. This is to make it easier for them to fly while learning the exceptional skills required to be effective hunters in their adult configuration. A falcon's wings are shaped like a scythe. Although common misconceptions of the difference of a scythe and sickle are the cause of the misconception of the shape of the falcons wings.

Peregrine Falcons are the fastest-moving creatures on Earth. Other falcons include the Gyrfalcon, Lanner Falcon, and the Merlin. Some small insectivorous falcons with long narrow wings are called hobbies, and some which hover while hunting 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.
