Friends of Big Bear Valley, responsible for webcams that provide 24-hour eagle access, posted footage of the arrival of Jackie and Shadow's third egg.

Bald eagle eggs typically hatch after 35 days of incubation, according to the East Tennessee State University. But Jackie and Shadow’s eggs will likely hatch after 38 to 39 days, or longer, since they have three eggs to tend to, the nonprofit said in the post.

Celebrity bald eagle couple Jackie and Shadow are preparing to hatch triplets in their California nest following last year's unsuccessful hatch.
