Bee hives...

That looks like a swarm of honey bees, your partly okay as long as they aren’t some of those wonderful Africanized variety. There’s a good chance of it with the hive being that large. But call a bee keeper ASAP. There’s enough difference between non Africanized wild bees and a swarm of domestic bees to make wild bees a risky neighbor. I used to get to help some neighbors move their beehives on occasion, so got to learn from those who know.
