Okay. Ever wonder why pigeons bob their heads? It's so that they can perceive depth. Animals with front facing eyes like ours can tell how near/far something is based on the angle formed by our eyes (called stereopsis). Pigeons, being side-eyed, don't have that option, so instead they compare the percieved size of things as they bob. Things that are closer will "grow" more than things that are far away.
