Most of the animals at Capron Park Zoo were born in captivity. For the most part, animals held in captivity in zoos are not collected from the wild anymore. The animals in the Nocturnal building are on a reverse light cycle. The lights are off during the day so that visitors can see the animals when they are active, then the lights come on at night so that the animals can sleep. The stuff in the animal exhibits is part of an environmental enrichment program.
Environmental enrichment gives the animals something to do in their exhibits and holding areas.
Enrichment items like boxes, balls and tubes help keep the animals busy and keep them from getting bored. Some animals in the zoo get enrichment 3 times a day. He is able to get his horns out of the fence. He does this often and always gets his horns out. He is just playing with the log.
