No one knows what was going through a cow's mind in Poland when she decided to escape from a farm last November — but one can presume she had an impulse to do something a little bit different.
She was spotted late last fall with a herd of wild bison, grazing at the edge of a forest. "It's not unusual to see bison near the Bialowieza Forest, but one animal caught my eye," Adam Zbyryt, a scientist who studies birds and the first person to see her with her new crew, said. "It was a completely different light-brown shade from the rest of the herd. Bison are chestnut or dark brown."
