Heard a loud buzzing yesterday late morning.
Went to the hive area and there were many bees about 100 feet from the hive, appeared to be swarming. A few minutes later the swarm was not around. The entrance of the hive had a lot of activity with a lot of large bees, thought the hive was being invaded but no real fighting, apparently drones but more than I had ever seen at my hive. Opened the hive this morning and there are several full and partial combs and plenty of empty bars. Hive is much calmer today with not many drones around just like it use to be.
Any insight on what's was happening?
