154. Elkhorn Slough, Moss Landing, California

A Globally Important Bird Area on the central California coast that attracts Long-billed Curlew, Whimbrel, godwits, and more than 300 other birds.

Caspian Terns congregating on mudflats, plump pelicans plunging their beaks into the shallows for food, and southern sea otters cracking open clams — at Elkhorn Slough, one of the largest estuaries in California, I’ve paddled alongside them all. And the mudflats have always been a great place to beach your kayak near Long-billed Curlews, Whimbrels, godwits, and other shorebirds.

The seven-mile-long slough provides much-needed habitat for more than 340 species of birds. The Elkhorn Slough Foundation, two state-run marine areas, and the Elkhorn Slough National Estuarine Research Reserve protect more than 8,000 acres of land and water. The slough is recognized as a Globally Important Bird Area and a Site of Regional Importance in the Western Hemisphere Shorebird Reserve Network.

Birding it from a kayak is a tranquil and unique experience. The mudflats are crowded with shorebirds and California Brown Pelicans, and farther back are egrets and Great Blue Herons. In addition to birding by kayak, visitors can walk five miles of hiking trails in the research reserve through oak woodlands, mudflats, and other habitats. — Chuck Graham
