Abstract: Aerial censuses were undertaken for Steller sea lions (Eumetopiasjubatus) and California sea lions (Zalophus californianus) during 1971-84, and a review was made of published and unpublished data on numbers seen and numbers killed since 1913.

These data were used to describe the location of haulout sites, season of occupation at haulout sites, regional movement patterns, and trends in numbers seen for each species during this century.
