Yellowstone Park Bison are culled to prevent them from following historic winter migration

I read an article on NPR.org that "Yellowstone Park Proposes Cull of 1,000 Bison This Winter." 

As in past years bison killed to prevent them from trespassing on traditional migration lands north of Yellowstone.  The report noted that "last year, park officials planned to kill up to 900 animals and actually removed 737.

This past summer I attended the Speak for Wolves meeting in West Yellowstone where the Buffalo Field Campaign presented graphic visual information about the continued hazing and senseless slaughter of wild bison in the Greater Yellowstone Ecosystem. Watch the video they produced below titled "Ten Miles of Hell"
