Today the Pitt peregrine chicks are 16 days old, fluffy white and weighing 1 to 1.5 pounds depending on sex. Male peregrines are always lightweight (about 1 pound at this age). Female peregrines are the heavy ones. We can’t weigh them visually so we don’t know their sexes.
You can’t see it on camera yet but the chicks’ flight feathers have just begun to emerge. It will be another four days before we’ll see the dark edges of their coming feathers. By then they’ll also have feathered faces.
Like all babies, these two spend their days eating and sleeping. In this Day In A Minute from Tuesday May 7 they have a very active moment at the front of the nest around 6pm.
The older they get the more active they’ll be. Watch them on the National Aviary falconcam at Univ. of Pittsburgh.
