2000 : Wolf-Bison

"10 bisons were killed by the wolves in 2000, accounting for 3 % of theirs total kills  (10 out of 113 definite kills + 210 probable kills = 10 out of 323 kills)"

"The Mollie’s pack has interacted with grizzly bears on a regular basis. During March and April, the pack killed six bison in six weeks and each carcass was usurped by grizzly bears within hours."

"As with Mollie’s pack, bison predation by the Nez Perce pack has typically occurred in late winter when bison are more vulnerable."

Bison kills included three calves, one cow, one bull, and four adults of unknown sex.
