What do bees do in the wintertime?

I live in regina sk, and it's way to cold for bees to be out and I want to know what they do.What do bees do in the wintertime?
They gather real close together in their hive and live off of the honey they have made all summer. Not all of them live of course but they keep the queen alive so the hive can expand its population in the spring.What do bees do in the wintertime?
The queen is in the center of the hive with the other bees around it. If the weather stays too cold for too long they may not be able to reach the honey in the hive and freeze. If they run out of food they can't stay warm. So they just kind of hang out until it warms up. A winter bee can live longer than a summer bee too. In the spring and summer they work so hard they only live 3 weeks.
Bees sleep all winter. when it gets warm out they wake up.
