Safety in Numbers

Some ocean fish swim in tight schools to evade predators. I wonder if crows do the same sometimes? Of course there aren’t all that many sky sharks or other large predators flying around for crows to worry about, so probably not.

While it might not be true for crows, I think it is true for flocks of starlings which are a food for various hawks and kites. Hence they congregate in large groups for safety in numbers.
What do you mean – haven’t you seen Sharknado?! 🙂
Guess I’d better check that out–my knowledge of sky sharks seems to be lacking!
