It was a big day Thursday for the National Zoo’s six-month-old sloth bear cub born last December–what with the climbing and exploring and posing and all. It was the debut public appearance for the Zoo’s first sloth cub born in seven years, named Hank after a vote from fans on Facebook. And he’s a bit of a rarity nationally with only 18 zoos exhibiting the species. Taking to the terrain quite nicely, he’ll now be a regular at his Asia Trail home every morning from 8:30 a.m. to 10:30 a.m. In case you missed his eventful first day, here are some photos from the Zoo.
