The Chopperbird[1] is a man from a foreign country disguised as an evil equivalent of the Helibird in the game Donkey Kong Jungle Beat. It very greatly resembles a Helibird, except for the fact that he has a different head, is colored red, and has two arms coming out of its torso.
The Chopperbird only appears as a rival in the first level of the Lemon Kingdom, "Chopperbird Race". In this level, Donkey Kong must use the various Helibirds stationed throughout the level to beat Chopperbird in a race. He does not have to beat him, but if he does, he gets 300 Beats. If Chopperbird loses the race, he will start flying around spastically, in frustration.
