According to the video description, music teacher Leigh Owens was cycling in his native Australia when he was attacked by the crazy magpie. The bird attacked the cyclist 10 times in 20 seconds. It looks like the magpie had some kind of vendetta against the cyclist.
According to description, Leigh Owens' "feud with the feathered friend has lasted three years — with the territorial bird attacking him dozens of times each year during its mating season."
