Swarm from one of my out-apiary hives. I couldn't be certain which. Probably either colony 4 or 12.
The swarm settled on a branch over 5m up. The weather turned just after they'd swarmed and they became stuck. I caught them when they'd been there for more than 3 days. Clumps of bees had fallen off and were stricken on the ground beneath the swarm. It took a cherry picker to reach them. I hived them in one of the National deep boxes with a Hamilton converter fitted (which makes them fit Commercial frames).
They were very weak when I hived them but appeared to be recovering after 18 hours in the hive.
