Keepers at the zoo have been monitoring the cub, which appears to be nursing, moving and behaving normally, the zoo said. They're also allowing time for the mom and cub to bond, which means it may be some time before veterinarians can determine the gender of the cub.

Visitors will have to wait a few months to see the cub in the zoo's exhibit. The newborn will have to undergo a number of health exams and vaccinations before successfully passing a swimming test.
