One of the first things you learn as a wildlife photographer, is to always leave some space in front of the animal - especially when it's moving. Clearly, I did not listen to that advice here. I had been shooting Japanese cranes (Grus japonensis) at this location for a couple of hours, and after sunset most of them left for their roosting spot. After a while they'd all flown away, but one. This was the last crane at the scene, and I photographed it like this because it looks like it's about to leave the frame, which was kind of appropriate. Rules are meant to be broken, especially when there's a good reason for it.
