this is the most amazing bird in the world, it can travel at 230 mph. I had the privilege of walking up on one in the Seattle area while it was eating a pigeon, I'll never forget it. I got within 12 feet. I froze and after a 10 second stare down it flew off without it's meal.
DDT causes the egg shells of these and other birds to become so thin they break under the weight of the sitting bird. Peregrine Falcon.
