High tides bring Pacific Herring into the bay to spawn several times a winter. The herring move into Richardson Bay to lay their eggs on beds of eelgrass (Zostera) and algae (Grasilaria), and the birds follow this energy-rich treat. Though most of what I saw today were gulls, scoters, scaup, and Bufflehead can all savor the occurrence. I took these photographs at a morning low tide, from the shoreline of Miller-Knox Regional Shoreline in Pt. Richmond. Seven species of gulls were observed: Mew, Ring-billed, California, Western, Herring, Thayer's, and hundreds of Glaucous-winged Gulls. Hybrids abounded, as well as first- and second-cycle birds.
