This might look like an egregiously misplaced school of fish, but it's actually an example of what ornithologists (bird experts) call a murmuration:
It's a flock of hundreds, and sometimes thousands, of tiny song birds called starlings. But exactly how these swarms decide to move and when with such a fluid motion is a complete mystery.
Within a murmuration, starlings are constantly on the move, so the shape is always changing.
But some photographers managed to capture some incredible, split-second moments of these flowing flocks that look strikingly similar to common shapes like a gigantic smoking pipe, goose, and sting ray. Check them out below:
