Diel Activity of Brown Bears in Plitvice Lakes National Park, Yugoslavia

We obtained 2,757 radiotelemetry activity readings, at 15-min intervals, from 2 brown bears (Ursus arctos) in Plitvice Lakes National Park. In late fall, while still with her family group, a yearling female was active during the day, but became nocturnal after her mother disapperared the following year. Her main rest period was from 0800 to 1600 hours, with a secondary rest period around midnight. An adult male followed a similar nocturnal schedule (Jul-Oct 1982 data only). Both bears were active 50%-60% of the time between July and October, 40% of the time in November and December, and 5% of the time in the winter den (Feb 1982, female only).
