Picked up the easiest swarm of my short bee keeping career (6 years). They were in a front yard on the ground in a pile the size of a super. It was in a grove of trees so I'm assuming maybe a branch broke and they fell. Put a super with frames in it over the top of them and propped up one side with the bottom board. Came back that evening and just picked box up and placed it on the bottom board. Maybe 20 dead bees in the grass, but the rest of them crawled up into box. Checked them today all is well. Wish they were all like that.
