WATCH | Gorilla learns to do a handstand

Bolingo the gorilla delighted his keepers when he did a handstand in his enclosure at Busch Gardens Tampa Bay in Florida.

According to a post on the zoo's Facebook page last week, this type of training enables the animal care specialists to "build trusting and positive relationships with the animals that call  the zoo home in order to provide them with the most mentally and physically stimulating environment possible".
