The British and Irish Association of Zoos and Aquariums (BIAZA) has announced the winning images in its annual photography competition. The 2020 winners show the important work of zoos and aquariums at an immensely challenging time. After months of closures, these conservation organisations are reeling from the financial impacts of the coronavirus pandemic.

Birds behaviour winner: Land of the Eagle by Audun Rikardsen, Norway. High on a ledge, on the coast near his home in northern Norway, Rikardsen carefully positioned an old tree branch that he hoped would make a perfect golden eagle lookout. To this, he bolted a tripod head with a camera, flashes and motion sensor attached, and built himself a hide a short distance away. From time to time, he left road‑kill carrion nearby. Very gradually – over the next three years – a golden eagle got used to the camera and started to use the branch regularly to survey the coast below.

Poisoned River. Abstract Winner. A detailed photograph of a stream filled with poison. “Poisoned Beauty” is a personal project that tells the story of the natural disaster in the Apuseni Mountains in Transylvania, which was a result of chemical waste generated by copper and gold mining, but in a beautifully abstract way.
