Jan. 27 (UPI) — A camera monitoring a bald eagle nest in California confirmed the birds of prey are now tending to a second egg near Big Bear Lake.

The camera, operated by the nonprofit Friends of Big Bear Valley, has been monitoring the nest of bald eagles Jackie and Shadow around the clock since the start of the season.

The nonprofit confirmed Jackie laid the duo’s first egg of the season on Friday, and the second on Monday.

“Bald eagles practice delayed incubation,” officials wrote in a Facebook post. “They intermittently incubate and stay off or hover over the egg(s) until the last egg of the clutch is laid.”

“Once the last egg is laid, they should incubate all the eggs more regularly. Since Jackie consistently lays eggs 3 days apart, this process slows the development of the first egg(s) laid so hatching will occur closer together, the eaglets will be closer in size, and all eaglets will have a better chance of survival,” the post said.
