The San Benitos Islands were not surveyed in 1977, although population information for 1973 was available. The total population in the region was estimated at 138 nesting pairs in 1977, but increased to 227 pairs in 1992 (Table 3). No nesting pairs were observed between the border and Desembarcadero de Santa Catarina in either 1977 or 1992. The first nesting pair was observed near Santa Catarina at 29° 35' N; 115° 22' W. However, from this point south to Morro Santo Domingo, an estimated 20 pairs were nesting on cliffs in 1977, but 31 pairs were nesting in 1992. Scammon's Lagoon has been part of the El Vizcaino Biosphere Reserve since.
