I am interested in what attracts the cluster in the first place. When they first exit a hive they apparently need to reorganize near the hive so all the swarming bees can find each other. They form the cluster and from there the scouts look for a permanent home.
From my experience evergreen trees are the "preferred" tree. This is a pure conjecture on my part. The cluster point also needs to be near the hive it exits. Is there a particular height of this cluster point that is the "preferred" height?
The "preferred" cluster point just may be what is available in that particular apiary. So each swarm will be different in what they prefer.
