Abstract
During parts of January and February 1964, observations were made on Galapagos sea lions. On Barrington Island one social group, composed of a dominant bull, females, pups, and immatures, was kept under observation for six days. The group slept at night on the higher beach. Activity began at dawn and all members of the group entered the water by shortly after sunup. Most of them returned to land within an hour or two. The dominant male permitted no other males in his territory. Stray bulls slept on the beach at night unnoticed. Females were observed nursing large immatures as well as pups. Lava lizards were seen on or near sea lions, where the lizards captured flies attracted by the larger animals.
