A Noisy California Gull Colony (Palo Alto)

California Gull by Mary Ann Robertson

Breeding California Gulls in the South Bay have been monitored since 1980 when there were only 24 gulls. A count in 2024 showed 7,201 nests at the Palo Alto Flood Control Basin; that is around 14,400 adult gulls! Very noisy. Add in the cute, fuzzy gray chicks and there is a lot to watch. We will walk the Adobe Creek Loop Trail to an area across from the basin islands used for nesting by California Gulls. There we will look for the chicks and some early fledglings for about 30 minutes. On the way back we will meander and look for shorebirds on Charleston Slough on the left and ducks and pelicans in Adobe Creek on the right. At the pump house we'll look for Barn and Cliff Swallows.
