abstract
Southern elephant seal pups Mirounga leonina were counted and tagged at .Marion Island (46�'S, 37�'E) between October 1980 and April 1981. The pups showed two distinct phases of movement, a post-weaning phase with eventual departure from the island in January, and a resting phase with pups returning to the island in March. Percentages of pups that moved during these phases were 16,9 and 18,9 respectively. There was no correlation between the stage of the season at which weaning occurred and the numbers that moved.
