That is likely a new swarm looking for a home. When an established hive gets too crowded, they will create a new queen who will then fly away with a subset of the workers to establish a new hive.
If you want to make your local beekeeper’s club very happy, call them and tell them where this swarm is! They will come and collect it.
Small detail: I believe the existing queen leaves with the swarm (~50 - 60% of the existing hive), while the bees that remain behind try to create a new queen.
