In our hive models, the entrance holes are always round. There are several reasons for this:
Natural tree cavities usually have a round entrance. Although there are also slits and other accesses. This probably doesn’t bother bees, because they are quite flexible. But generally speaking, bees have made their home in ancient woodpecker cavities for millions of years.
Round entrance holes are very easy for bees to reach. Many records Round flight hole entrances are very well defended by bees against threats and allow for much more efficient aeration. This is further enhanced by a longer flight hole channel which results from the thick insulation of our hives.
The round flight holes allow the air in the hive to be balanced in a suitable way by means of propolization (narrowing of the entrance). This allows the bees to control the air themselves and to better regulate the climate inside the hive against temperature fluctuations from outside.
A flight hole at the bottom assumes that the heat in the habitat is optimized. The heat rises to the top. This is where the honey, so important for the winter, is produced. In winter the cluster of bees moves towards the honey in a warmer area, which is in principle favorable.
