A few nice animals that are extinct images I found:
Red Kite (Milvus milvus)

Red Kite (Milvus milvus) that I saw flying and gliding around near Walkern, Hertfordshire, on 23 April 2011. It was a lot closer to me than the Buzzard I photographed recently was, but by the time I got my camera out, it had moved away. Not brilliant photos but a rare opportunity.
Almost extinct Red Kite makes comeback
