Friends of Big Bear Valley announced the news on Facebook on Monday with a clip from the live camera feed at the nest perched on a tree in Southern California's San Bernardino County. The nonprofit has been monitoring the eaglets, named Sunny and Gizmo, since they hatched in early March.

At 10:46 a.m. Monday, June 2, Sunny, one of the two eaglets that have captivated hundreds of thousands of fans across the world in recent months, fledged, leaving her sister, Gizmo, behind, according to Friends of Big Bear Valley.

Sunny, one of the bald eagle chicks hatched by Jackie and Shadow in March, has finally left the nest. KCAL News spoke to Friends of Big Bear Valley Executive Director Sandy Steers about the exciting moment on Monday.
