There is nothing unusual in this. Bees do not hibernate, and if the weather
is still and sunny, they will make quick journeys outside on cleaning
flights. You don't say where you are (a common failing) but if your
temperature rises above 10C. and there is little wind, then the bees will
normally fly and if there is food, they will go for it. They only have the
food stored in the hive to last the winter so if they can gather outside,
it's a bonus.

Little buggers still didn't see fit to pollinate my unseasonaly flowering
broad beans, though. :-(
