Most of the feral bees around here behave as if they are AHB. Every swarm I've tried to hive in the past eight to ten years, abscond almost immediately after I get them into the hive. A few years ago, before I began importing queen stock from elsewhere, then raising my own queens from those mother queens; would behave similarly. A good example is when I attempted a split; I took half of the bees, brood, pollen, and honey and placed them in their own location, the next morning they had absconded, leaving the brood (lots of it open) and pollen, but taking the honey with them. They had not returned to their parent colony, but were gone to parts unknown. What motivates them to do this? I can only guess that they have their reasons for obsconding, but other than something that would be obvious to us, like unhabitable conditions in the new location/hive, it is difficult to know what the bee's reasons are.
