PITTSBURGH (KDKA) — Just hours after the hatching of the first Hays eaglet of 2021, a pip has appeared in a second egg.

Expert eagle watchers, observing the new baby, spotted the new pip around 7:30 a.m. when the mother eagle got up and began rolling her other eggs.

A “pip” is a “visual sign of a hatch in progress,” says the Audubon Society of Western Pennsylvania. The time from pip to hatching takes about 12-48 hours.

The Audubon Society says the newly hatched eaglet likely weighs about 3.5 ounces.

The first eaglet took about 48 hours to emerge after the pip was initially spotted. It was first seen sitting in a half shell around 3 a.m. and finally rolled free from the shell around 4:21 a.m.

The fuzzy baby is covered in soft gray down that will eventually be replaced by thermal down in about 14 days. That means the babies cannot initially maintain their own body temperature.

It takes about nine days for eaglets to develop better eyesight.
