Sandy and Luna eaglets could fully develop at any time. Both hatched in the first week of April, which puts them right at the upper end of the average 10 to 14 weeks to fledge. This means that they could leave the nest permanently at any time.

To practice a more independent life, they have spent more time jumping from trees and eating the fish that their parents, Jackie and Shadow, bring to the nest.

On June 28, Sandy accidentally left the nest, when she and Luna walked onto the “front porch” of the nest. Luna then tried to jump over Sandy to return to the nest bowl, but Sandy lost her balance and fluttered towards the lower branches. He broke free of the branches and landed on another tree.

Eaglets usually depend on their parents for two to three months after fully developing. They will learn to hunt and improve their flying skills. Last year’s eaglets, Sunny and Gizmo, left the nest at 90 and 91 days, respectively.

After fledging, Sandy and Luna may appear in the nest chambers from time to time, as they are expected to remain in Big Bear Valley for a while. However, they are not marked, so your activity will not be fully tracked.

Big Bear Bald Eagle Live Nest – Camera 1


It’s been another roller coaster nesting season for Jackie and Shadow, a pair of internet-famous bald eagle parents who live in the San Bernardino National Forest in Southern California. After crows destroyed two of their eggs in January, Jackie and Shadow laid two new eggs that hatched successfully.

Chick 1 hatched on April 4 at 9:33 p.m. PDT, while chick 2 hatched on April 5 at 8:30 a.m. Their large nest in Big Bear Valley, east of Los Angeles, is broadcast live 24 hours a day by the nonprofit organization Friends of Big Bear Valley (FOBBV) and has captivated millions.

On May 1, FOBBV announced the names of the chicks: Sandy and Luna.

How long will the chicks stay in the nest?

Chicks usually remain in the nest until 10 to 14 weeks of age.

What challenges do harriers face?

Before leaving the nest, the chicks face threats from other birds of prey, including hawks, crows, other eagles, and owls. Inclement weather can also present challenges for chicks. In 2025, a snowstorm in March caused the death of one of Jackie and Shadow’s three chicks.

During fledging, only 70 percent of the eaglets survive. One of the biggest threats is cars that can injure or kill birds as they forage for roadkill.

Who are Jackie and Shadow?

The pair first met in 2018 and successfully raised chicks in 2019 and 2022. However, their eggs did not hatch in 2023 and 2024. Only 50 percent of eagle eggs hatch successfully, so this couple has already beaten the odds.

What happened to Jackie and Shadow’s 2025 eaglets?

In 2025, Jackie laid three eggs that hatched in early March. On March 13, a severe snowstorm dumped up to two feet of snow and battered the nest with high winds. Only two of the chicks were visible on the live camera when the storm passed the next morning. The FOBBV later confirmed the death of one of the chicks. The two surviving chicks were later named Sunny and Gizmo after fans submitted 54,000 names.

What happens after the chicks fledge?

Young eagles usually fledge (or leave the nest and fly) when they can flatten their wings and have feathers capable of flight. This usually occurs when the birds reach 10 to 14 weeks of age. Males also tend to take their first flight a little earlier than females.

According to FOBBV, Southern California chicks have been seen as far south as Baja California, as far north as British Columbia, and as far east as Yellowstone National Park.

About 70 percent of bald eagles survive the initial stage. The FOBBV does not tag its eagles, so it is not possible to follow the chicks’ journey after they flee the nest.

Can I help Jackie and Shadow?

Yes. Environmental groups are currently fundraising $10 million to protect the Jackie and Shadow feeding area from development. Learn more at SaveMoonCamp.org.
