4 Beautiful eggs with inside growing embryo's. They are now around 22 days old. This picture shows what the embryo's look like now, at this age. A real little chicklet. Notice the enormous eyes compared to the size of the skull.
The eyes of the peregrine falcon are very special. His eyesight is phenomenal. It has to be, for
flight depends on vision. A blind-folded bird cannot take off or fly properly because it is unable to orient itself. As predator bird ancestors adopted flight, they needed ways to find generally small prey (such as fish and small rodents) from the air; they needed abilities to see at close range; and they needed to maintain focus at high speeds when in pursuit. The most successful birds of prey in any population were those with eyes better adapted to these demands. Over thousands of generations, natural selection led to populations of predator birds with greater visual capabilities. Like the peregrine falcon.
