In years past it seems that swarms were in cluster for hours if not days. This year over half of the swarms that I have tried to capture, have left the area within one hour of coming out of the hive.
This past Sunday two hives in my backyard (The ones I let do thier own thing) swarmed simultaneously. They ended up clustering within 5 feet of each other 40 ft up a tree. Not being able to do much I just watched as both swarms within the hour (10 Minutes apart) flew off over the tree tops and disappeared.
Maybe its coincidence. Maybe the crappy spring and compacted season. But these bees seem to be on a mission and sitting around waiting for me is not part of it. Two other beekeepers have mentioned the same thing. Now I'm thinking maybe there is something to it???
