Back in 1961 the lieutenant Nils Egel turned his attention to a colony of penguins at Edinburgh Zoo. With his active assistance, one of the birds were given the name of Nils Olav and even awarded the rank of corporal. After each visit of the Royal Guard to the Edinburgh parade of military bands, Nils Olav was increased in the post. In 1982 he became a corporal, and in 1987 - Sgt. However, after receiving the title he died, and was replaced by Nils Olav II. In 1993 Penguin "promoted" to the Regimental Sergeant, in 2005 was promoted to Colonel-chief, and in 2008, and at all was knighted.
