The Assiniboine Park Zoo announced Friday it’s now featuring two baby pronghorn.

“They were about two kilograms at birth and we are excited to say they are healthy and growing fast,” said Gary Lunsford, general curator at the Assiniboine Park Zoo, in a statement.

The pronghorn babies are siblings and are now one month old.

Pronghorn range from Canada down to Mexico.

“Though they are not true antelope, they are often referred to as ‘pronghorn antelope’ due to their resemblance,” said the zoo.
