Along the west shore of Richardson Bay, Bothin Marsh is an example of what the wetlands surrounding San Francisco Bay and San Pablo Bay looked like before they were channeled, diked, and filled. During fall and winter, migratory waterfowl thrive in the open water and sandpipers and other shorebirds feast on the invertebrates that are found in the mudflats. We’ll also look and listen for year-round residents like clapper rails and common yellowthroats, which inhabit the surrounding cordgrass and pickleweed. This walk is for ages 15 and up. We request that no pets (except service animals) attend. Rain may cancel. If questionable weather, call (415) 893-9527 after 7am on the morning of the walk for a recorded message to see if the walk is cancelled.
