Swan are beautiful birds, but, much like their goose relatives, they can be proper a**holes. This wake surfer learned just that on a Texas lake, when a swan attacks and causes him to fall off his board.
There are a whole host of reasons why swans might aggressive, but they get the worse when they’re protecting their young or foraging for food. Back in 2012, a swan knocked a man off his kayak. When the man tried to swim to shore, the bird appeared to have blocked his path, and the man eventually drowned.
