Seabirds

Marine birds are known to concentrate in upwelling areas of the monument, largely around the canyons. These areas have high productivity and subsequent food availability, resulting in large concentrations of birds. Several species of gulls, shearwaters, storm petrels, gannets, skuas, and terns, among others, regularly occur here in large aggregations. Researchers have recently discovered that Atlantic puffins are overwintering here because of the abundant food. Prior to 2015, no one knew where these charismatic birds spent their winter months!
