The last time they did this, they swarmed.
Bees sometimes beard at the entrance when the hive is too hot, but last night at 8 pm it was a balmy 62 degrees, not hot enough for bearding. Even though the entrance was completely blocked, bees carrying pollen still managed to get inside. When it’s humid in the hive, honeybees will also beard at the hive entrance like this, but it’s the first time I have seen this behavior in my colony. I guess it’s a good sign my population is up and it’s getting crowded in there. Amazing, considering the obstacles that stood in their way this year.
