Again, it’s probably normal behaviour for honey bees, but I haven’t seen it before so, as usual, I’m concerned. I checked out the hives first thing this morning and noticed an abundance of wasps flying around. It was also after the first frost of the season. I mention these facts just in case they’re significant. Other than the wasps, there was little activity. I checked the hives again around 11 o’clock when both would be in full sunlight (they only get a couple hours of direct sunlight at this time of year) and there were bees everywhere. Hive #2 looked great. Orientating flights, foragers coming and going. No complaints. But the bees in Hive #1, which haven’t been too active in the past week, were pouring out of the hive. Not flying around much, just walking out of the hive and hanging outside on the entrance board in a thick carpet of bees.
This photo shows them clumped together on one side of the entrance, though the entire entrance board was covered with bees. It’s now about an hour later and they appear to be coming and going as normal, though they still seem to be favouring one side of the entrance.
Does anyone know what would cause the bees to gather in large numbers around the entrance like that? I heard the buzzing of some angry-sounding drones. Maybe they’re all getting the final boot today. I know sometimes bees will hang outside the hive on hot days, but it’s only about 12 degrees out there. It’s not that hot. Anyway, I’m just curious (I’m not alarmed). Here’s the video:
