The pair of Peregrine falcons that makes its home in a nest box high atop a downtown Boise skyscraper has something special to guard in the box now: Four eggs. The Peregrine Fund and Idaho Fish & Game report that both the mama and papa Peregrines have been carefully incubating the eggs, and the webcam is on; you can watch online here, and hear the birds’ vocalizations as well. Eventually, viewers will get to watch the eggs hatch and see the young peregrine chicks grow and fledge – learn to fly and leave their nest.
