Polar bears in the wild commonly spend the majority of each day traveling to locate prey; captive polar bears commonly spend several hours a day in locomotor stereotypies preceding their scheduled daily feeding time. Experiments 1-4 presented small samples of food and scents on several schedules...

Similar reindeer response behavior from encounters with a polar bear and persons disguised as polar bears ...
