Chickens bob their heads back and forth so that they can see while moving about. Unlike you or me, they cannot keep their focus on a point and move their heads at the same time. Chickens have a pretty advanced version of image stabilization for their cameras. Don’t have an anti-shake camera stabilizer in your camera? Have a chicken handy? Great! Just strap your cam to its head and watch as nature’s image stabilization service does all the work. There you go: easy image stabilization.”]
