Bees getting stuck in the stuck

Sometimes bees will get stuck in the sky.

 

I'm not sure why it happens but sometimes I'll come across one or two bees that get stuck in the sky. My place is situated in a village and there is a bee that is stuck above a cobblestone fence. Another two are stuck at the top of a giant oak tree. While one more is just stuck above the ground (or a flower). They are a dozen blocks above the ground and usually get stuck around the same amount of height. I throw snowballs at them to get them unstuck lol. It does the trick. Until one of them gets stuck again...

That's all I know. Hope you can fix this! Thank you!
