The National Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) initiated a long-term marking program of northern fur seals (Callorhinus ursinus) at San Miguel Island, California in 1975. A sample of up to 300 pups has been tagged in the foreflippers with various types and colors of tags each year between 1975 and the present. Resighting surveys for marked animals are conducted annually at summer breeding sites. Resightings are also obtained from the public when animals are observed on beaches or in fisheries. The data are used in mark-recapture models to estimate the age and sex specific vital parameters of the population and to describe age and sex specific reproductive behavior and seasonal movements of animals throughout their lives.

Supplemental Information
Submission Package ID: L95XFP
Purpose Estimates of age- and sex-specific survival and natality are used in population models to assess the status and describe trends of the northern fur seal population. Data are also used to describe life history traits such as age at first reproduction, dispersal patterns, and lifetime reproductive patterns.
