Swans are big and mean. My neighbor has a pair and they are not something I would want wandering around my yard. They will charge you if they think you are too close plus they poop all over the place.

I chased off their "small" cousins, the Canadian Geese from my dad's lawn when I watched their place. I grabbed my old hockey stick from back in the day and was the most demonstrative I could be in showing aggressiveness. It looked ridiculous to see a 30-something with a hockey stick flailing away running after them, but it worked. Those birds understood what "get out of here I'm dominate" means and fled without attacking or hissing. They didn't come back.

I would not want to go near a swan nest. That would be a nasty fight or flight.

Yep, they have nasty dispositions....but like a charging goose, stand your ground and when they are almost on you, grab them by the neck just behind the head, when they are lifted up off the ground, you can throw them far enough away to not get bitten...nasty beaks if like a goose, serated like a steak knife....they attack just like a goose, run at you flapping their wings.

Sorry, but that’s the point where you kill the damn things. Don’t care how big and how mean...if someone’s going to die, critter’s going down asap.

A gaggle of geese or a flock of swans make a very effective replacement to guard dogs.

Plus, they will make a racket while taking down someone.
