Here's an update on the pair of Peregrines who are nesting on the
Washington Mutual Tower in Seattle. Two of the four eggs hatched
yesterday. The first hatched sometime before 3:40 AM (that's when an
egg-shell fragment popped out from under Bell, the female). The second
hatched around 8:30 or so in the morning (the same thing happened...).
Both eyasses appear to be healthy. The other two eggs are showing
signs of "pipping".
