Jason Moore, a photographer from Australia, has won the top award in the Comedy Wildlife Photographer of the Year competition, for a photo he took of a kangaroo that looks like it's playing air guitar. Moore was visiting an area outside Perth, in Western Australia, when he saw a group of kangaroos playing, and some were responding to music. He snapped the award-winning photo and titled it "Air Guitar Roo."

The competition, founded by Paul Joynson-Hicks and Tom Sullam, dates to 2015. It is free to enter, and the winner this year, Moore, won a safari in Kenya, a camera bag, and a trophy. Moore's was one of 5,300 entries from 85 countries. Contest rules allow contestants to enter up to 10 images and two videos.

Winning the Junior category was Jacek Stankiewicz, 16, from Poland, who captured a photo of a pair of birds, one of which looks like it's telling the other bird to get lost. Stankiewicz titled his photo "Dispute." He also won the People's Choice Award.

Other categories included Creatures of the Air, Under Water, Portfolio, and Video.

Joynson-Hicks, who lives in Tanzania, founded the competition in 2015; Sullam joined him a few years later. Both are ardent photographers and strident conservationists.
