The Columbus Zoo says about 70% of the animals in the North America region were either displaced by natural disasters, orphaned, rescued or rehabbed due to injuries. After the long trip, the calves arrived at the zoo Tuesday and are now exploring their new habitat in the North American region. The calves, named Bert, Scarlet and Violet, are estimated to be roughly 5 months old. They were all found by the Alaska Department of Fish and Game and were being cared for at the Alaska Zoo prior to their arrival in Columbus.
