There is a 2-3 year old female white buffalo (Bison bison) in the small herd at Jamestown, ND. The park and pioneer village also contains the world's largest bison, a giant concrete sculpture visible from Interstate 94. In July of this year the female gave birth to a normal colored calf. Keepers of the herd didn't even know she was pregnant. The father is presumably one of the two adult bulls in the herd. This white bison did not originate in this small herd, but was brought in from elsewhere.rich r
