17 May 2021, 16:32 BST This image of a young male gorilla by the edge of a stream in Bwindi National Park won Kathleen Ricker the grand prize and title of PA2F Environmental Photographer of the Year 2021. Photographer Jean-Michel Krief, member of the jury and co-founder of the Sebitoli Chimpanzee Project in Uganda, said Ricker had “perfectly captured the magic of the moment when the gorilla forgets [Ricker's] presence to concentrate on crossing the river in the heart of the sumptuous Ugandan forest."
