Dalmatian pelicans on Lake Kerkini in Greece captured over the space of one week (16-21 January 2023) by tour guide photographer Sean Weekly. The Dalmatian pelicans resemble the winged dinosaur pterodactyl as they swoop, splash and feed in the waters of Lake Kerkini in Greece. With wings outstretched, and colourful faces and beaks on display, the birds appear to be in paradise, with the awe-inspiring Kerkini mountains as a mesmerising backdrop.

Respect, Kronotsky nature reserve, Russia. The photographer’s cat, Ryska – her name means little lynx in Russian – stands outside their cabin and with aggressive posturing warns off a fox. In winter, foxes would regularly visit the cabin searching for food. If one peered in at the window, possible when the snow was deep, Ryska would sit on the other side, fur raised, and growl. When outside, she would hold her ground. The foxes were not always frightened and so encounters could be a sort of dance. (Photo by Igor Shpilenok/Unforgettable Behaviour/NHM)
