This is the only time i've ever seen the tiger at the SD zoo, and this duck landed in his enclosure. he stalked him and watched him for about 3 minutes, and then pounced on him, tore his head off, and tore all his feathers off. It was the coolest thing i've ever seen at the zoo. The only regret I have was that I only had my little powershot, and it wasn't really fast enough to capture all the action. I really wish I had my 40d.
