Last week I went down to the street to collect the garbage bin and gathered up a few pieces of litter in the yard that escaped the truck. As I got close to a tree near the street, I could hear buzzing and witnessed this!

So the wife got in contact with a beekeeper who said he would try to come get them but it wouldn't be until later. About an hour later I went down to look at the bees again and THEY WERE GONE!

The wife called the beekeeper to see if he had got them and he had not. Apparently they flew away on their own.

I looked around the yard and didn't see any swarming.
