Today I sat out next to the hives and watched what was going on and heard, and saw, many (dozens) drones flying in and out of the hives. Drones are somewhat larger than worker bees and make a louder sound when flying. The workers were bringing in lots of yellow and orange pollen. This indicates that they are still raising young.
The drones were still flying in and out indicating they are still looking for virgin queens to mate with. Kind of late in the season but I imagine this has to do with the fact that queens can die any any point in the season and if a hive need to requeen itself to survive this can happen at any time of the season.
Drones (2) notice the big eyes
