Canon Lens and the Birds

I always wanted to photograph birds and now it is possible thanks to a camera upgrade from Canon 400D to the new Canon 600D plus my super new lens! I bought the Canon 400mm L 5.6 after borrowing one from a friend. I have not looked back since I bought this lens in April. I love nothing more then taking the photos and now I am painting and making montages from my avocet pictures.
