KEARNEY, Mo. (AP) — The national mammal of the United States is getting in on America's 250th birthday celebration.

Three bison statues cast in bronze have taken up a permanent display outside the Smithsonian’s National Museum of Natural History in Washington. The pieces — which are larger than real-life bison — made their public debut in the nation's capital on Friday.

The bison earned its official status as the nation's mammal under a law signed by former President Obama in 2016. Millions of bison once roamed the Great Plains but were nearly driven to extinction in the 1800s.

“It’s a wonderful story of conservation working, it’s a story of people seeing a need and getting behind that to conserve an animal that is specific to North America,” said Gary Staab, a paleoartist who made the statues.

Staab designed and sculpted the statues in Kearney, Missouri, where he works full-time to create sculptures of animals and historical artifacts for museums around the world. For the bison, Staab sculpted the full-size statues in foam and clay before they were cast in bronze and assembled at a foundry in Colorado. The three statues depict a bull, a cow and a calf.

He said it took about four months to complete the sculptures — a time frame he called “lighting fast” given the size of the pieces.

“They really represent a really unbelievably beautiful and unique thing about North America,” Staab said.
