The eagles are back! More precisely, a nesting pair of bald eagles has returned to Lake Chabot Regional Park in Castro Valley, and it looks like they are raising two eaglets.
Golden eagles are fairly common in the East Bay, especially in the area of Altamont Pass. But nesting bald eagles are more rare around here. They're not bald -- the adults have distinctive white-feathered heads. The bald eagle, America's national bird, appears on the nation's seal.
The nest is located in a restricted area of the park. It's in a dense eucalyptus grove, hard to see, but visible from across the lake through binoculars.
From the West Shore Trail, look across the lake to trees on the peninsula between Half Moon Cove and Bass Cove. From the dam, you can see the adult bald eagles flying to and from the nest. Viewing may be even better from a boat on the lake.
"This is now a mature, 6-year-old female eagle, and she has successfully raised a chick here the last two years," said Doug Bell, the East Bay Regional Park District's wildlife program manager. "We ask that eagle-watchers stay on the trail or in their boats, so please observe our rules to protect the birds," he added. "Landing boats on shore or entering restricted areas of the park is not allowed."
Trespassers are subject to citation.
Bald eagles have been seen in previous years flying over and around Lake Chabot, and in February 2012, they built a nest there for the first time. One juvenile bald eagle hatched in 2012, and a second one, raised in a different nest, fledged in 2013.
If all goes well, the current pair will fledge in July. The U.S. Fish and Wildlife Service does not list bald eagles as endangered or threatened. However, they are protected by the Bald and Golden Eagle Protection Act and are still listed as endangered in California.
The entrance to Lake Chabot is at 17600 Lake Chabot Road in Castro Valley. Parking costs $5 per vehicle. You can rent a boat with electric trolling motor at the marina. The fishing is generally good, too, for eagles and people, because the lake is stocked frequently with trout and catfish.
