After nearly three months of speculation, the experts have weighed in: Both eaglets at the Big Bear bald eagle nest are female.
Sunny and Gizmo are sisters, according to the organizations that operates the world-famous 24-hour camera feed of the nest near Big Bear Lake.
“Peaceful, loving sisters,” added Friends of Big Bear Valley Executive Director Sandy Steers.
Sunny practices catching the wind under her wings while Gizmo watches with fascination at the Big Bear bald eagle nest on Friday, May 30, 2025.
The naturalists announced last week that Gizmo was believed to be female, but Sunny’s sex remained unclear until Saturday.
“After much observation and some fairly definitive vocal frequency analysis, we believe that even though Sunny, as the older one, is now smaller than Gizmo, she is also female,” Steers said in an update posted to social media.
Despite being four days younger, Gizmo has outgrown Sunny in size.
When will the Big Bear bald eaglets leave the nest?
Although now the smaller of the siblings, Sunny has led the way when it comes to exploring the branches surrounding the nest and experimenting with flight.

She was seen taking to the air for a 3-second-long hover above the nest for the first time on Thursday.
Her flight testing grew bolder and Friday, when she was again spotted hovering above the nest and spreading her wings into the wind.
Bald eaglets generally leave the nest, or fledge, at 10 to 14 weeks of age, experts said.
At 12 weeks old, Sunny and Gizmo could each be ready to make their first flights away from the nest any time now.
But they won’t immediately become strangers.
Eaglets tend to remain close to their nests for a month or two as they develop the skills they will need to survive on their own.
They young predators will then head out to establish their own homes, potentially hundreds or thousands of miles away from Big Bear.
They still have a long journey ahead of them, as bald eagles mature at a slow rate.
Sunny and Gizmo aren’t expected to develop their iconic white heads, like their parents Jackie and Shadow, until they reach 4 or 5 years old.
