Taken at Bass Rock, located in the outer Firth of Forth, Scotland, a pair of "billing" northern gannets.
Bass Rock is home to one of the largest concentration of northern gannets anywhere in the world. Their numbers were decimated following the devastating bird flu outbreak in 2022 but in 2025, using drone technology, researchers counted over 50,000 nests on this small island, suggesting a population of over 100,000 birds.
Mated pairs engage in a "billing" display, a mutual greeting and bonding gesture where two birds stand breast to breast with their necks and bills extended rubbing their beaks and entwining their necks.
