If lack of food triggers it, what triggers the bears to come out of torpor?

The sound of running squirrels, I guess.

Jokes aside, maybe the smell and environment turning from winter to spring. They mention these happen to black and brown who are omnivorous, so smell of food that's easily accessible is most likely. Just a guess.
