Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of environmental enrichment. Three elephant cows at Kolmårdens Djurpark were observed during night to map their nocturnal behaviors and see how they changed with feeding enrichment. The elephants were lying down on their sides 25 % of the time observed. With feeding enrichment offered in the morning, the stereotypies was reduced in one individual from 43 % to 13 % (P<0.01) and the foraging was increased in two individuals from 45 % to 80 % (P<0.01) and from 45 % to 64 % (P<0.05). Increased food access increased foraging behavior and as environmental enrichment was able to reduce the stereotypic behaviors in these Asian elephant.
