This mother pronghorn and her youngster were hanging out in Grand Teton National Park.

While the little baby was as hyper as could be – jumping, running and prancing around, the mother was all business, keeping a watchful eye for predators.

The pronghorn looks quite like an antelope (but isn’t), which is why many people call them pronghorn antelopes.

Amazingly fast, the pronghorn is said to be the fastest mammal in all of the Americas! The Cheetah in Africa is believed to be the only land animal that is faster than these graceful creatures.
