Heermann's Gull (Larus heermanni) on Salmon Creek Beach, 5 July 2012
Of the 14 gull species documented on Bodega Head, Heermann's Gull is one of the most distinctive. This is an adult. Note the all white head contrasting with the gray body, and the two-toned bill (red with black tip).
Most of the world's Heermann's Gulls (90-95%) nest on one island in the Gulf of California (Isla Raza). After nesting, they migrate north along the Pacific Coast, generally arriving in our area around mid-late June. Most will depart for Mexico in mid-late fall.
