Brother Michael: good to hear your bees are doing so well. Keep us posted.
Some thoughts:
The sun is everything to a honey bee when it come to navigation. The waggle dance directional point is based on position of the sun and the bees account for the time of day. As we know the morning, mid day, and afternoon sun are in different positions and the bees understand this and account for changes in sun movements with their waggle dance. Actually the sun is not moving, the earth is.
The bees fly back to the hive not so much by eye site rather by a built in gps which is thought to be based on magnetic fields if the earth. Want to test this: stand close to the front of the entrance, say 6 feet and you will be slammed by returning bees because they are not looking. Also, move a hive just 6 feet and bees will return to the original empty hive position and circle. The hive can be just a single isolated hive with no other hives around to cause confusion. One can look and easily tell it the same hive, just moved only 6 feet but the bees trust their gps more than eyesite. Eventually the bees will figure out the hive was moved but not before circling many minutes trying to figure why the hive is not where it is supposed to be.
To be clear, I am not saying bees do not use their eyes, certainly for landmarks, flowers, to chase the beekeeper, etc. I am saying GPS is a majority navigation system relied upon by the bees.
BTW, honeybees have five eyes, two large and 3 little tiny eyes.
Blessings
