Laysan Albatross Phoebastria immutabilis
Vagrant, primarily winter and spring, in Offshore region.
eBird records since 2010: May 16, 2015.
Habitat: Open ocean far off shore.
Note: Despite a new colony established in 1986 on Guadalupe Island, Mexico, only 200 miles south of San Diego County, the county's ocean waters are generally too shallow for this species. Single birds seen from shore near Point La Jolla in 2015 and 2016 were also likely Laysan Albatrosses but too far to eliminate even more rare options.
