An understanding of pinniped haulout behaviour can provide information on how animalsinteract with their environment, their foraging strategies and the behaviour of their prey. ForWeddell seals Leptonychotes weddelli, knowledge of haulout patterns and the environmental driversof haulout is comprehensive for the austral spring and summer, but is poorly described outside thisperiod. Pinniped behaviour is commonly examined using satellite telemetry; however, it is unclearwhether the behavioural state of the seal can itself influence data acquisition. We examined hauloutbehaviour of female Weddell seals in eastern Antarctica over 3 winters (March to August, 20062008)using satellite-linked data loggers. Haulout behaviour followed a diel cycle with predominantly nocturnalhaulouts. The environmental variables wind speed and temperature were influential onhaulout, with seals tending to haul out more in lower winds and at higher temperatures. Hauloutduration decreased across the winter, as did the number of satellite uplinks, suggesting that hauloutduration played a role in data acquisition. There was no evidence of a decline in tag condition overthis period, indicating that the decrease in uplinks was primarily the result of the winter behaviour ofthe seals.
