Bees have been regulating brood nest temperature for a couple of years before humans started keeping them (actually millions of years). A tree may be more insulated and more efficient at removing moisture which I think is more important; however I think you can over play our role in bee keeping. It is much more efficient, (for my dog) if I carry her down the street but the point is taking her for a walk. I think it best to let them adapt and make it there home, they know what is best for the colony, if your hive is not a good home they will let you know. Also tree bound colonies tend to be much smaller in number although Im sure there are some exceptions more bees might need a more ventilated less efficient hive. .....?
Excellent photos though, very neat perspective.
