262. Santa Maria River Estuary, Guadalupe, California

One of the best places to bird in Santa Barbara County, this estuary is great for shorebirds, seabirds, and waterfowl.

The Santa Maria River Estuary has long been considered one of the best birding hotspots in Santa Barbara County. More than 200 species have been reported, and it is a breeding location for the endangered Western Snowy Plover and California Least Tern. One of the best shorebird spots in the county, it is also an Audubon-designated Important Bird Area.

In the fall, you might see thousands of shearwaters on the horizon. Gray whale sightings are relatively common from shore. The wintering flocks of ducks, geese, and sandpipers are quite impressive, and Northern Shovelers may number in the thousands.

The adjacent beach is famous for its heavy surf, and the surrounding dune complex is one of the largest in the United States. Birding the estuary and beaches can be easy or strenuous. It is an easy hike to the beach or the estuary. However, to walk the entire length of the accessible beach and estuary can be several miles through loose to packed sand. For the more adventurous, a 2.5-mile walk (5-mile round-trip) south along the beach yields incredible views of Mussel Rock, a breeding area for Pigeon Guillemots. — John Deacon
