Peregrine falcons are the fastest animals in the world. They can dive at speeds well over 200 miles per hour! Also called the duck hawk, these widespread birds are found on every continent except for Antarctica. History: In the 1950s, 60s and 70s peregrine populations in North America declined in many parts of the world due to pesticide use, particularly DDT. Many birds were killed due to a build up of the poison in the rodents they consumed, which had eaten poisoned insects. Peregrines are also commonly used in falconry, the practice of training birds to hunt on command. These birds have been used in this way for over 3,000 years! Scientific Name: Falco peregrinus Characteristics: This peregrine falcon is swooping in to grab some prey in its outstretched talons! Size:  Our peregrine falcon toy figure features a wingspan of 3 ¾ inches, and is 1 ¾ inches long and 2 ¾ inches high, making it just about the size of a standard sticky note.
