The now very familiar grizzly bear sows 610 and 399 along with their cubs have continued to put on quite a show for area residents and visitors. But we are into December now and bears typically hibernate in the winter. Grand Teton National Park Spokesperson Jackie Skaggs explains that hibernation is typically linked to the availability of food and a major snowstorm or blizzard. With the annual elk reduction program ending Sunday, carcasses will become scarcer and park biologists think the bears will likely head into their dens in the next week or two. Curiously, says Skaggs, 399 has a history of “pushing the limits” and likely will again be one of the last to go into hibernation – possibly as late as the third week of December. In the meantime, the bears are taking advantage of final opportunities to consume a large amount of calories to see them through the winter weeks as they make final appearances in front of the cameras of local wildlife enthusiasts.
