Swans are beautiful creatures and there is no doubt in that. But these animals can also be dumb. There are many instances when you will find swans way too stupid, just like in the video below. Thankfully, here a man untangles swans from a deadly lock to save them from choking each other.
It is not pretty sure where the video was taken, but we can assume that some humans were present there. The way these swans came up to the humans for help gives the impression as if they have known the humans for a long time. Swans are pretty aggressive when it comes to protecting their nests. There is a folklore that even says that once a swan made a man drown protect its nest. So, seeing swans coming ashore to ask help from humans might sound quite unusual.
