WHICH BIRD DO YOU THINK IS THE FASTEST?

https://en.m.wikipedia.org/wiki/List_of_birds_by_flight_speed

This is a list of the fastest flying birds in the world. A bird's velocity is necessarily variable; a hunting bird will reach much greater speeds while diving to catch prey than when gliding.

The bird with the greatest airspeed velocity is the Peregrine falcon, able to exceed 320 km/h (200 mph) in its hunting dives.
