To watch: Bald Eagle Live Cam.
The egg was laid on Saturday, February 14, 2015 around 6pm The birds will take turns incubating an egg for about 35 days, with one of the birds seldom leaving the nest. Eagles can lay up to five eggs one after another, but typically only lay two or three.
Once hatched, an eaglet will hang around the nest with its parents keeping it warm and feeding it. It eventually takes its first flight and by mid-July, an eaglet will flee the nest.
