A polar bear rolls around in dead grass at Seal River, Manitoba, Canada

A quick break from Yellowstone to check back in on the polar bears.

The reason mid October to mid November is the best time to go to northern Canada to observe polar bears is because they are all waiting around for the ice to freeze on the Hudson Bay so that they can go hunt seals. In the meantime, they’ll do anything to kill time, including rolling around in a pile of dead grass, like this guy here, providing plenty of photo opportunities.
