Consisting of more than 50 acres of restored salt marsh, Arrowhead is part of the 1,220-acre Martin Luther King Jr. Shoreline, a jewel of the East Bay Regional Park District. Narrow channels connect shallow San Leandro Bay with the broad waters of San Francisco Bay farther west. Protected from high waves but subject to strong tides, Arrowhead’s mudflats and salt marsh provide rich bird habitat, and the park service is eradicating introduced spartina plants, making the marsh even more attractive to birds.
I look for three rail species at high tide and hordes of wintering shorebirds on the mudflats at low tide. In the summer I can find 40 species, including many newborn stilts and avocets, and it’s possible to top 60 species on a fall or winter day. Almost any Pacific shorebird or raptor is possible during fall migration. — Harry Fuller
