276. Kern National Wildlife Refuge, Delano, California

More than 225 species have been recorded at this refuge in the Central Valley.

Kern National Wildlife Refuge is a crown jewel in a thin chain of parks and refuges that stretch along California’s Central Valley like a dark green necklace. These tiny islands in an ocean of agriculture and urban development support more than 300 species of birds as they ply the Pacific Flyway.

The refuge is managed for waterfowl; as many as 80,000 ducks and geese overwinter on Kern’s pools, marshes, and scrub grasslands.

I particularly enjoy driving slowly along the refuge’s auto loops that meander among the pools. Before dawn, the refuge awakens to a cacophony of goose and duck calls from distant shapes in the twilight. Later, early morning flights of waterfowl can be spectacular sights, especially when raptors unexpectedly appear, sending ducks and geese exploding into the sky. I often have better luck finding raptors than songbirds here. Harriers and Red-tailed and Red-shouldered Hawks are common, and sometimes a Peregrine Falcon or Golden Eagle will come into view.

Early spring, beginning in late March, brings passerine traffic. This is when I pay more attention to brushy riparian areas and remnant forest patches.
