A resilient pair of internet-famous American bald eagles is at it again. Jackie and Shadow are currently incubating three eggs on their large nest overlooking Big Bear Lake in the San Bernardino mountains east of Los Angeles, California.

Friends of Big Bear Valley say they may have seen the remains of a missing third eaglet in the nest. "We know that both the possibility and the uncertainty are hard to hear," the organization said.

Concern turns to grief after fans learned that a chick of Big Bear bald eagle couple Jackie and Shadow had died in a winter storm.
