If you spend any time at all outdoors with a camera, you should try your luck in one (or all) of these contests. Even though the competition may be daunting, it’s always worth a try, and there are some really nice prizes up for grabs.

Wildlife Photographer of the Year Now in its 45th year, this contest brings out the best of the best when it comes to wildlife photography. It’s open to amateurs, professionals, and youths, and there are many different categories: Animals in their Environment, Behavior, Underwater, Animal Portraits, Plants, Urban and Garden wildlife, Nature in Black and White, Creative Visions of Nature, and Wild Places. It’s 20 to enter (for up to 3 photos). For each category, the jury selects one winner and one runner up, who will receive 500 and 250 respectively.

The three youth categories – 10 years and younger, 11-14 years, and 15-17 years – are free to enter, and you can submit up to 10 photos of landscapes, plants and wild animals. Here also, one winner and one runner-up are selected from each category, and are awarded 250 and 100 respectively. The winner of the grand prize, the ” Young Wildlife Photographer of the Year” receives 500 and the opportunity to spend a day shooting with a well-known wildlife photographer.

In the three special awards, the requirements are a bit more specific. For The Gerard Durrell Award for Endangered Wildlife award, you need to submit photos of species listed as critically endangered, vulnerable or near-threatened on the 2008 IUCN Red List. The Eric Hosking Award is open to photographers aged 18-26, and participants are required to enter a 10-image portfolio. The One Earth Award focuses on conservation, and they are looking for images that encourages respect for nature. The winner of each category is awarded 1,000.

The Wildlife Photographer of the Year winner gets 10,000, presented at a ceremony at the National History Museum in London. Deadline for 2009 is March 27, but if you don’t make it, don’t worry. Remember, it is an annual event, so you always have next year.
