Knighted penguin named 'Brigadier Sir Nils Olav' at Edinburgh Zoo

Sir Nils Olav is not your ordinary penguin. The sir is a king penguin, the second-largest penguin species, and was adopted by the Edinburgh Zoo in 1972. He was named after two people: Olav, King of Norway at the time, and Major Nils Egelien, who organized the adoption.

Sir Nils has had an eventful life at the Zoo. After he made it his home, he became the mascot of the Norwegian Guard. Since, he has rose the ranks from Corporal all the way to Knighthood.

On Monday, the Edinburgh Zoo hosted the Norwegian Guard -- and Sir Nils was in attendance, of course. They posted a video of the ceremony on their Facebook page:

The Guard gave the penguin another honor following his 2008 knighthood. "Already a knight," the Zoo wrote, "the most famous king penguin in the world is to be given the new title of 'Brigadier Sir Nils Olav.'"

The ceremony occurred with 50 soldiers as well as His Majesty the King of Norway's Guard.

Sir Nils Olav -- Brigadier Sir Nils Olav -- waddled down with pride.
