Bison family

Three adult bison graze on grass. Two calves flank them, also grazing. Two more calves to the right of the herd lie in the grass. Behind them, fence posts, metal fencing, trees and some buildings.

On May 14, 2021, a group from the bison herd, including some of its newest members, graze on the Fermilab campus. Photo: Mark Sloat
