BEARDING IN FRONT OF THE BEEHIVE
But why are the bees grouped like this? We assure you, it's nothing serious! When they form a cluster outside the hive, they are said to be "bearding".
In the event of a strong honeyflow, a strong colony and high temperatures, the bees sometimes move outside their shelter. It is not possible for them all to stay inside due to lack of space and/or stabilisation of the temperature at an acceptable level. In principle, there is intense ventilation at the flight entrance.
