Oh my, how these “guys” have grown! Actually, 3 females and 1 male. If I were to guess, I would say that the last one to hatch is the male. It just looks smaller, even at this stage in their development. The Peregrine Fund put a great post on the falconcam site about their development and activities at this age. Interesting.
You may be noticing that the chicks are becoming much more active now that they’re a bit older and are actually jumping out onto the ledge on occassion. They do eventually jump back into the nest, but this is a normal part of development for nestlings. Soon, they will enter a stage of life where they’re referred to as “branchers.” During this stage, chicks will spend more time out of the nest and flapping their wings. This helps to build muscle so that their breast muscles are ready to support their wings in the air when they take their first flights.”
