Warning: This video might be upsetting to some readers.

Director Roel Wouters has created this controversial but compelling video for the band zZz. Normally birds are given barbs and spurs when fighting so that they cut each other. This was not the case for this video. Also the inks are apparently animal friendly and after the video the animals were found to have no injury. You be the judge. Check out the making of video after the jump.
