175. Santa Rosa Plateau Ecological Reserve, Murrieta, California

A reserve halfway between L.A. and San Diego where you can see California specialties, wintering Lewis’s Woodpeckers, and migrant warblers in spring.

Nestled at the southern end of the Santa Ana Mountains, this wild place is one of the last areas in southern California where you can see rare Engelmann oak woodlands, hillsides covered in chaparral, and vernal pools. The fleeting bodies of water, California specialty birds, and wintering Lewis’s Woodpeckers are the main draws for birders.

For the best birding, walk on any of the trails in the morning hours. You often don’t have to go far to see Wrentit, Hutton’s Vireo, California Towhee, California Thrasher, and Lawrence’s Goldfinch. In spring, I usually start at the Vernal Pool trailhead to check for dabbling and diving ducks, shorebirds, White-faced Ibis, and raptors.

Near a group of historic adobes, I check the 400-year-old coast live oak for nesting Acorn Woodpeckers and migrating warblers, then head out on the Adobe Loop Trail. It passes through a riparian area that can hold some of the best birds, including warblers, orioles, Western Tanager, and nesting Pacific-slope Flycatcher. On my way back to the trailhead, I stop to listen for Blue Grosbeaks singing in an old olive grove. — Charity Hagen
