Egg Number...Two!

Right on schedule (eggs are laid every 2-3 days), the 2nd egg was in the nest this morning!  The average clutch for peregrines is 4 eggs.  While the adults may cover the eggs for short periods of time at this stage, actual incubation won't begin until most of the eggs are laid (probably after the 3rd egg).  In the meantime, the eggs just stay in limbo and don't begin to develop until they are receiving uniform and consistent warmth from the incubating adult.
