The Wildlife Photographer of the Year competition, founded in 1964, is an annual international showcase of the very best in nature photography. The competition, co-owned by the Natural History Museum and BBC Worldwide, opened for entries on January 5, and will stay open until February 26. This year, the contest includes 21 individual categories, ranging from birds and mammals to "In the Skies" and "TIMElapse Special Award." The owners and sponsors have been kind enough to share the following 10 finalists from last year's competition. Their website has images from all of last year's winners and more information about the current competition.
