JACKSON, Wyo. (AP) — One of the best known grizzlies in Grand Teton National Park has postponed her hibernation by more than a month this winter.

Grizzly 399 and her two cubs were spotted Monday near Pilgrim Creek, possibly headed to her den.

Most female grizzlies in the Yellowstone area start hibernating in November but 399 has been known to stay out until Dec. 12 before.

The Jackson Hole Daily (http://bit.ly/yHYExc ) reports that the lack of snowfall may have delayed 399's hibernation this year. The park's senior wildlife biologist, Steve Cain, said the elk hunt have also allowed her to feed off carcasses and remains left by hunters.

399 is well known for spending time near roads and developed areas with her cubs, attracting a following of scientists and tourists alike.
