^Before 1980, Heermann's Gulls were known to breed only in the Gulf 

 of California and along the west coast of Baja California, Mexico. Two pairs 

 attempted to nest at Shell Beach in 1980. These represent 2 of 3 known 

 nesting attempts by Heermann's Gulls in the state of California in 1980; 

 the other being at Alcatraz in San Francisco Bay (Binford 1980). All 3 

 nesting attempts were unsuccessful. See Appendix B.
