Once in the swarm cluster, these foragers now become scouts and are in search of a relatively large (between 20-60 liters of volume.), relatively enclosed cavity space with a single entrance around 2 square inches. These scouts seem to award bonus points to nest locations that already have drawn honeycomb or leftover queen pheromones from previous colonies. The scouts measure the volume of these nesting sites, usually a hollowed out tree or perhaps a hole in a concrete wall, by walking and flying the length, height, and width of the surfaces. The scouts will not discount a site do to small holes or even debris within a cavity that can be removed. Once satisfied with the measurements and quality of the site, the scout returns to the swarm cluster, still sitting in a ball on the branch of a tree or bush.
Back with the cluster, the scout will begin a waggle dance on the backs of her fellow bees indicating the distance and direction of this new nest site. The number of times that this scout dances indicates to the other scouts the quality of the site. The longer she dances, the higher the quality of the site. For every second a scout waggles indicates how many 1000 meters from the swarm cluster the prospective nesting site is. The direction is expressed by the direction in relation to straight up (straight up being the direction towards the sky) the waggle dance is oriented. For example, 20 degrees to the right of straight up indicates that the other scouts must fly 20 degrees to the right of the sun in its current position in the sky. Other scouts take note of this waggle dance performance and use the directions expressed by the scout to go and check out the prospective nest sight. These dancing scouts are quite literally voting for a particular nesting site. Once enough scouts agree on the best possible location, the dance is continued to inform the rest of the colony the direction and location of the new nesting site.
At this point the swarm will take off, usually travelling at a minimum 250 yards from their old nesting site. While in flight, these same scouts that have made multiple foraging and scouting trips throughout their lifetime will steer the swarm to the new site. Oftentimes the swarm will have to break briefly for a tired, overweight queen who is not accustomed to flying long distances.
Once at the new nesting site the bees will begin rapidly building comb in order to facilitate the rapid growth necessary for survival. Only one in four of these new colonies will survive the first year.
