Experience, (not study) is that in my yards, they either move nearly
exactly 90% to prevailing wind, exactly down prevailing win or nearly
directly above the originating colony as their initial settle point. I
have never had a swarm move any other direction (that I have found) in
any other direction.
        They also tend to settle in the same spots and issue between 11 and
2:30 during the day. I also note the bees performing flying practice
come out about 1 hour before the temperature drop enough that foraging
effectively ends.
