A penguin which was previously made a Colonel-in-Chief of the Norwegian Army has been knighted at Edinburgh Zoo.
Penguin Nils Olav has been an honorary member and mascot of the Norwegian King's Guard since the 1972.
Over the years, he has been promoted through the ranks after being adopted by a Royal Guard who visited the zoo.
However, the penguin honoured on Friday is unfortunately not the original Nils Olav.
He died in the 1980s and was replaced by a two-year-old penguin at the Zoo.
Norway presented the zoo with its first king penguin in 1913, the year of its opening.
