[1] The character of a parrot was derived from the classic story Treasure Island by Robert Louis Stevenson, most notably the one owned by Long John Silver named "Captain Flint".

The Pirates put out a casting call for highly-energetic candidates, hoping to find a comedic talent similar to Robin Williams, and selected Kevin Koch after an extensive audition day due to his disco dance skills.

[3] In one game, an older grounds crew member kicked the Pirate Parrot in the head and threw a rake at him after the character jumped on the man's back.

The following year, all three mascots took part in a groundbreaking of an expansion of the National Aviary in Pittsburgh, with Steely McBeam tossing dirt at the Parrot's feet.

[11] Kevin Koch (pronounced "coke") was the original Pirate Parrot for seven years after its debut in 1979, selected over 97 other applicants for his energetic nature and talented disco performance during his audition.

[12][1][13] Popular among fans for his lively dancing, Koch reportedly lost 17 pounds his first season due intense physical activity and sweating.
