Sir Nils Olav, a resident of Edinburgh Zoo, is the only knighted penguin in the world, having received the honour in 2008.
A Norwegian family presented the zoo with its first king penguin in 1913.
The current Nils Olav is actually the third penguin to bear the name, since penguins only live about 15 years. He’s named after Major Nils Egelien, who organised the adoption in 1972, and the then-King of Norway, King Olav.
He’s also an honorary member of the King of Norway’s guard and was promoted to the title of Brigadier in August 2016.
