Peregrine Falcon Development - Age Guide
The photos below chronicle the development of a peregrine falcon chick from hatching through to fledging. All photos are from the 2002 Rochester, New York nest, captured via the Kodak Birdcam and reproduced here with the kind permission of Kodak. Note that while these photos represent a fairly typical progression of development, the rate of growth does vary slightly among different birds.
