A picture of a hunting wolf has won the prestigious Veolia Environment Wildlife Photographer of the Year 2009 award.

Jose Luis Rodriguez captured the imaginations of the judges with a picture that he had planned for years, and even sketched out on a piece of paper.

"I wanted to capture a photo in which you would see a wolf in an act of hunting - or predation - but without blood," he said. "I didn't want a cruel image."

With a great deal of patience and careful observation of the wolves' movements, he succeeded in taking the award-winning photograph.

Mr Rodriguez used a custom-built infrared trap to snap the wolf as it leapt into the air.

The WPY competition, now in its 45th year, is owned by BBC Wildlife Magazine and London's Natural History Museum.

The panel of judges looked through more than 43,000 entries to this year's competition.

This is the fifth year that wildlife photographer Mark Carwardine has been on the judging panel. He said of the winning photo: "It's captured thousands of years of human-wolf interaction in just one moment."
