(CNN) — A breathtaking image of a peregrine falcon attacking an enormous pelican with its bright orange talons won top prize in this year’s Bird Photographer of the Year competition.The contest, in its eighth edition, celebrates the beauty of birds while also raising awareness of the mounting pressures they face. Photographers from all over the world entered more than 20,000 images into the competition, all vying for the £5,000 ($6,280) grand prize.US photographer Jack Zhi, who took the winning image in southern California, says he had waited for four years to capture the rare moment when a female falcon pounced on a brown pelican more than double its size.“During breeding season, a female peregrine falcon fiercely protects her young, attacking anything that comes near the nest,” he explained in a press release. “The high-speed chase made it challenging to capture a close-up shot with a long lens.”But finally, he succeeded. “The action was fast, and over in the blink of an eye.
