What is the fastest bird in the world?

The fastest bird in the world is the peregrine falcon (Falco peregrinus), which can reach speeds of over 380 kilometres per hour (236 miles per hour) in a dive. When hunting, peregrine falcons tuck in their wings and dive from great heights, swooping down on prey with incredible speed. Their aerodynamic body shape and keen eyesight allow them to spot and catch prey from a long distance. Peregrine falcons are found worldwide and are known for their remarkable hunting abilities and adaptability.
