Which bird is capable of speeds up to 386 km/h (240 mph) in a stoop (high speed dive)?

So far, no bird is known to match the flying speed of a Peregrine falcon in its hunting dive. The Peregrine falcon is the fastest bird – and in fact the fastest animal on Earth – when in a dive. As it executes this dive, the Peregrine falcon soars to a great height, then dives steeply at speeds of up to 240 miles (386 km) per hour. The video above gives you an idea of how fast this is, as seen from the falcon’s point of view.
