This is a collection of powerful images from past years of the Wildlife Photographer of the Year competition - the most famous and prestigious event of its kind in the world. Taken by photographers who are skilled in storytelling and reportage, each image carries with it an unforgettable story, often a message about the current state of the natural world. Sometimes these involve individual characters, but always there is a bigger story behind the immediate one. Such images require not only photographic skill but also an intimacy with the subject and considerable research and dedication. They have been taken by more than 50 award-winning photographers representing nearly 20 countries.
