Looks like a cloud of bait fish on a graph; but it's in the sky? Kind of funny of how the bird flock and the fish school look about the same? Mast together but are still individual. Nature sure does have some strange crap happening.

Even cooler when you see something like this. In the spring we have swarms of bugs flying around the shore of Erie. They fly in the same type of patterns and the swarm sounds like a pool pump running which is what I thought it was the 1st time I heard it. Thought it was the neighbour getting the pool online. Then we saw the clouds of the bugs moving back and forth up and down and looked like a swirling cloud of smoke. Mother Nature sure is amazing she is.

There is also a large bird looking for lunch!
