I've seen one get pissed at a car honking at it to get out of the way (they're a protected species, Canadian Geese, specifically), and it actually ripped the license plate off his front bumper with its beak and like held it in its mouth threatening the guy to step out of his car and do something about it.

Was the wildest shit I've ever seen. Like something out of a Miami throw down, except it was a goose and a car.
