Peregrines are wide ranging birds found all over the world, and there are currently 19 recognized subspecies. Three of these are found in North America. In the 1950s, 60s and 70s peregrine populations 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. However, recovery efforts have helped the peregrine’s numbers become more stable in many areas of within its range.
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!
