Swarming

I was away from Oxford for the last week of June. It seems that there was a swarm on the tree in front of my out apiary on 28th June. I suspect that this was from Colony 4.

I have no real evidence that this swarm was from any of my hives. There seems to be less going on in Colony 4 -- less pollen on the hive floor for example -- but I can't be sure.
