The Norwegian King’s Guard has visited Edinburgh Zoo to promote resident king penguin Sir Nils Olav to the rank of brigadier. Sir Nils is the third penguin of the same name at the zoo, following a tradition initiated in 1972 by a Norwegian lieutenant, Nils Egelien. The penguins, which have become a symbol of the close relations between Norway and Scotland, were named after Egelien and the then Norwegian king, Olav V, father of the current king, Harald V. Norway presented the zoo with its first king penguin when it opened in 1913.
