A year after he was seriously injured in a close encounter with a bison in Yellowstone National Park, a Massachusetts man has fully recovered from the traumatic experience that made international headlines. Robert Dea, 59, of Newbury, Mass. had planned a two-week sumer vacation to Yellowstone and a Montana guest ranch with his wife and their friend in June 2012. But he ended up spending eight days in the hospital instead, after being tossed around by a bothered bison. Continue Reading →

When hundreds of bison move through a small town like Gardiner, Mont. at the north entrance to Yellowstone, they have the potential to damage property, injure people and transmit disease to livestock. Park managers and other wildlife agencies try to reduce those potential conflicts, but don't always know where and when the animals will move, said Chris Geremia, a National Park Service researcher at the Yellowstone Center for Resources.

Bison migrating out of the North Gate of Yellowstone National Park during cold and snowy weather will have some extra room to roam following a ruling by a Montana judge. District Court Judge E. Wayne Phillips on Monday dismissed a lawsuit brought by state and local livestock groups that sought to block a plan that would allow bison to move throughout a 70,000-acre "tolerance zone" of mostly federal land north of the park.

Viral video of ‘Bison Fury’ shows need for safety around Yellowstone, Grand Teton wildlife

An Aug. 4 video posted to YouTube illustrates the importance of keeping a safe distance from wildlife in Yellowstone and Grand Teton National Parks. (YouTube video)

With fall approaching in the high country of Yellowstone National Park, animals are moving to lower elevations, prompting park officials to issue a seasonal warning about staying clear of wildlife. Proving the point, a viral video of a Yellowstone bison chasing a boy is attracting plenty of attention online. Park regulations require people to stay at least 100 yards from wolves and bears, and 25 yards from other large wildlife like elk and bison. Both bison and elk become more aggressive during their seasonal mating periods, and park officials want to make sure visitors don't get too close. That's exactly what happened in a 90-second vacation video called Bison Fury, viewed more than 100,000 times since it was uploaded Aug. 4 to to YouTube. Continue Reading →

It happened at Otter Creek in Yellowstone National Park in October. The female bison (known as a cow) wasn't feeling very well. You could tell that just by watching her. She was lethargic, and never moved very far away from a small meadow she had chosen. Had she felt better, I would have expected her to join the bison herd less than a mile away. It was also pretty clear that the wolf knew she was vulnerable. Continue Reading →

A Wyoming photographer whose work captures both the majesty and the savagery of wildlife in Yellowstone National Park says she is drawn by the irresistible lure of the park's animals, and though she loves photographing bears and wolves, she is "always rooting for the elk calf." "I understand the food chain," said Wapiti, Wyo. wildlife and nature photographer Sandy Sisti. "But I still don't like to see anything suffer." Continue Reading →
