I few days ago I posted a question asking what my bees were doing and there was a difference of opinion. One said it was an large orientation flight and the other a swarm. Well they are doing it again, a large group of bees exiting the hive flying around for a while and then returning. When I took this video, it appears they were all returning to the hive (the hive with the brown box was not involved; it always has bees hanging out). Swarm or Orientation flight?
