30. Cosumnes River Preserve, Galt, California

This bird-rich preserve just south of Sacramento is home to almost 300 species of birds.

It is nearly possible to forget the modern world here. Early mornings, when the first rays of sunlight filter through the canopy of valley oaks and vines, are my favorite. I have the sense that just about anything could hop into view. You just never know.

Recently, two friends and I began a bird-a-thon listening for waterbirds before dawn along Desmond Road, about three-quarters of a mile north of the visitor center. We heard the reedy whistle of Northern Pintails, the harsh call of a Dunlin, and the “oinking” of Virginia Rails but failed to record the hoped-for Least Bittern. As the sky brightened, we rushed to the forest as its birds became active — including eight species of warbler lingering late in the season. After a full day spent scouring the preserve’s wetlands, forests, and grasslands, we had found 128 species.

The 80-mile Cosumnes is the last undammed river flowing from the Sierra Nevada into the Central Valley. Its natural flooding cycles promote regeneration of wetlands and forests. The preserve has grown to 46,000 acres, including some of the best remaining valley oak riparian forest, plus wetlands, grasslands, and wildlife-friendly agriculture in an otherwise rapidly developing region. — Chris Conard
