dc:abstract Abstract We report on the duration of the post-weaning fast and describe the behaviour of southen elephant seal weanlings, Mirounga leonina, born at Peninsula Valdes (PV), Argentina. Resights of marked animals were conducted throughout lactation and postweaning fast. Mean (+/- SD) duration of the fast was 45.5 +/- 7.9 days, and mean age at departure for the same animals was 67.5 +/- 8.0 days. Pups born early in the season (first two weeks of September) remained ashore about nine days longer than those born near and after peak season (first week of October; 48.7 +/- 7.2 vs. 40.4 +/- 6.9 days, respectively). Mean post-weaning travel distance from the beach of birth was 6.8 +/- 4.2 km, and increased with age. Weanlings were inactive most of the time (90 % of 257 daylight hours). Time spent resting (90 %) decreased during ascending tides (75 % - 65 %). Twelve days of continuous activity recorded with data loggers deployed on four animals showed that animals were more active at night and that more time was spent in the water during ascending than descending tides. The duration of the post-weaning fast was longer for the expanding PV population than for other populations of the species.
