Looks like someone needs a break from all the excitement!

After being introduced, it didn’t take long before rhinoceroses Natal (right) and Nabire got down to business Friday: taking a nap.

A southern white male, 38-year-old Natal was brought to the zoo in Dvur Kralove, Czech Republic in hopes of keeping their resident northern white female, 27-year-old Nabire, company following the death of her previous roommate, a 39-year-old female northern white named Nesari.
