First egg of year laid in Hays Bald Eagle nest

PITTSBURGH — The first egg of the year was laid in the Hays Bald Eagle Nest, according to the Audubon Society of Western Pennsylvania.

The egg was first seen just before 6 p.m. Friday. Once the female eagle laid it, she stood up and rolled it.

Now that there is an egg in the nest:

An adult Bald Eagle will stay on the nest constantly, incubating the egg.
The adult eagles will take turns on the nest, never leaving it unattended.
When the adult stands up, it can be seen rolling the egg to keep a constant temperature within the egg. When this occurs, the egg is visible in the nest bowl. The adult then lays back down over the egg to continue incubation.

Officials said there is usually a 2-4 day span between laying eggs. The Hays Bald Eagles have been nesting on the same hillside since 2013.
