There isn't a lot that I can add to this picture, it's obviously a Robin coming in to land.  I have been working for weeks trying to get  perfect flight shots of  small birds, it's a real challenge, they fly remarkeably quickly and you need a shutter speed of  at least 1/3000 of a second but preferably 1/4000, lots of luck and perfect light!  I had perfect light this evening, all I needed was a few birds and a lucky shot.  The luck is the shutter firing at exactly the precise moment that the bird passes through the sweet focus spot, an inch nearer or an inch further away andit would be out of focus. I am chuffed with this picture!
