Only one in 10 million American bisons are born white. And now, one of these rare animals can call Pennsylvania home.

A white American bison was born on April 29 at the Living Treasures Wild Animal Park in Donegal Township. The male calf -- named Liberty -- was born days before President Barack Obama signed a law that makes the American Bison the county's national mammal.

"We are proud to have him join our family and are happy that he and his species are getting the recognition that they deserve," the park said on Facebook.

This is the park's second white bison. The park's first was Liberty's mother -- Buttercup.

The Living Treasures Wild Animal Park wrote on its Facebook page that the white American bison have long held sacred and spiritual value to Native American communities.

Over the past several years, there have been a number of rituals performed in honor of the 5-year-old Buttercup.
