On Earth Day, two peregrine falcon chicks hatched in their pebble nest on top of the University of California, Berkeley’s Campanile Bell Tower. The chicks hatched within hours of each other on Monday morning, with their parents Annie and Archie closely watching over them. The chicks will quickly dry off and their down feathers will turn into a warm, cozy pile of fluff, while Annie will nibble on eggshells to regain the calcium she used to create the eggs. There are still two more speckled eggs that have not yet hatched, and you can watch the Cal Falcon Cam’s livestream from the nest at calfalcons.berkeley.edu.
