In “The nest of the honeybee” in 1976, Tom Seeley describes a random alignment of the entrances in tree caves inhabited by bees. Unfortunately, he does not give data on the alignment of uninhabited tree caves in the region. It is therefore not possible to verify whether the bees prefer a certain direction for the entrances of their tree caves or not.
Comparison with two studies of natural hollows in general in our latitudes suggests that its description is correct. In these studies, the orientations of all cave entrances are documented, irrespective of whether and by whom they are inhabited.
All three regions are situated in the western wind zone and have a similar climate. The percentage distribution of the cave entrances is almost the same in all three regions. Obviously, the bees do not prefer a certain orientation of the entrance hole.
