This Black-headed Heron (Swartkopreier) passed the camera on 25 Jan 2010 at 7 pm. It is a juvenile bird and does net yet have its adult colours.

Notice how the head of the heron stays at exactly the same position even though its body position changes so much

Yes, I did notice, and you know why that is? It's because the eye of the bird sees MUCH better when it is at a standstill, unlike other vertebrates. Check out Wikipedia's "bird vision" at http://en.wikipedia.org/wiki/Bird_vision
