This is the only beach along the San Mateo coast where western snowy plovers nest. The small shorebirds, listed as "threatened" under the Endangered Species Act, can be seen in the largest numbers during the winter months. Between 40 and 50 have been spotted at the beach most days in January and February.
Other regular sightings include great egrets, northern harriers, kestrels hunting in the fields east of the beach, long-tailed weasels, voles, mice, and other small rodents.

The Pescadero Marsh Natural Preserve, a part of Pescadero State Beach, shelters a diversity of wildlife in a complex of several habitats—a tidal estuary, freshwater marsh, brackish water marsh, dense riparian woods, and northern coastal scrub. It is an important wintering ground for waterfowl on the Pacific flyway.
In winter, visitors on the twice-monthly, docent-led nature walks have seen as many as 35 different species of birds, including great blue herons, great egrets, and snowy egrets, and many varieties of ducks, including gadwalls, American widgeons, northern shovelers, green-winged and blue-winged teals, pintails, ruddy ducks, common goldeneyes, and buffleheads.
Fewer ducks are seen as spring approaches, as migratory ducks begin to fly to their northern breeding grounds. In March, however, great blue herons put on an impressive display as they begin their nesting season in the tall eucalyptus trees that line one shore of the marsh.
You never know what you will see when you walk through the marsh. A Western pond turtle was spotted basking in the sun on February 1, and the wildflowers in spring are delightful.
