Aug. 15: Nils Olav, an Edinburgh Zoo penguin and colonel-in-chief of the Norwegian King's Guard, an elite unit tasked with protecting the Norwegian royal family, inspects soldiers of his regiment as they visit him in Edinburgh, Scotland, where he was presented with a medal. The original Nils Olav became an honorary member of the regiment in 1972, when a young lieutenant called Nils Egelien visited the penguins at the zoo, but died in the 1980s and was replaced by the current Nils Olav.
