The National Geographic Photo Ark is a travelling exhibition of photographer Joel Sartore’s quest to create a photo archive of biodiversity around the world. So far, Sartore has captured studio portraits of more than 6,000 species – a number that he hopes to double. On 1 July, the ark will open at Melbourne zoo – the first time it has been exhibited in the southern hemisphere. More than 50 portraits will be on display, including many of Australian endangered animals being protected by programs at the zoo itself. These captions have been edited from text supplied by Melbourne zoo. Here: Barking owl. (Photo by Joel Sartore/National Geographic Photo Ark/The Guardian)

Andrew Parkinson, animal behaviour category winner: Crepuscular Contentment, Derbyshire. “In 15 years of working with badgers I’ve never seen a badger sit out in the open to have a scratch. I was sat concealed behind a tree and downwind so it was especially nice that the badger had his back to me, demonstrating just how inconspicuous and inconsequential my presence was”.
