Nature: category shortlist

Presenting the winners and shortlist for the magazine's first ever photography competition.

Adrian Wray, Oxfordshire
"We waited for hours for the wildebeest in Kenya's Maasai Mara to cross the river. Suddenly, one decided to go, then another, then another. Snorting, mooing, splashing, the noise was incredible and the dust became a cloud that swept through the trees. A crocodile toyed with the odd calf, but was so bloated it didn't bother to kill. And a few minutes later, it was all over."
