Bird Rock is a rock formation and a small Pacific island west of Tomales Point in Marin County, California that is roughly 2 acres (0.8 ha).
A seabird colony, the island is covered with a layer of guano. Cormorants are common on the island, [2] and ashy petrels were found breeding there in 1972. [3]
