504 feet per hour is about one-two-thousand-five-hundredth as fast as a Peregrine Falcon.
In other words, it's 0.000395 times the speed of a Peregrine Falcon, and the speed of a Peregrine Falcon is 2,530 times that amount.
(a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)
The Peregrine Falcon can reach speeds of up to 1,280,000 feet per hour when diving. Falcons are sometimes sent to scare smaller birds away from airports to improve air traffic safety and were used in World War II to intercept carrier pigeons used by enemy forces.
