Sixteen miles long, Lake San Antonio features a resident herd of more than 400 black-tailed deer, up to 100,000 migratory waterfowl, and the largest wintering population of bald eagles in Central and Southern California. More than 50 bald eagles, 12 resident golden eagles, and ospreys roost on shoreline snags.
The best viewing is from the county’s large tour boat, which provides information and binoculars. In the spring, golden eagles nest in trees near the shore. Canada geese, Clark’s and western grebes, American white pelicans, wood ducks and herons gather on the lake; miles of muddy shoreline are proved by American avocets and killdeer. Resident acorn woodpeckers, wild turkeys, and California quail are joined by many migrants, including California thrashers, cedar waxwings, and yellow-billed magpies.
High probability of seeing eagles and other birds of prey from December 15 to March 10. Also see waterfowl in winter. American white pelicans from fall through early summer. Look for songbirds in spring and summer. Deer, bobcats, and squirrels are seen year-round.
