(it's unusual to open a hive in the winter).Is it because bees don't like the cold?
Is it because bees don't like the cold?
Yeah, they hunker down and don't forage as much. Also since they aren't as busy, they get grumpy faster. Best time to open a hive is a fine Spring day when they are busy as, well, bees :-)
What do they do when they aren't... buzzy?
Who knows? It doesn't freeze here, so they do some foraging all winter, here. Colder places they only fly to collect water occaisionally in winter, and spend a lot more energy (honey) generating heat with physical activity.
