Notes:

In season 2 of Plunderstorm, this blue parrot is purchasable from the 'Plunderstore', using currency earned during the event. During the original Plunderstorm run it was the reward for reaching Renown 20 with Keg Leg's Crew.

Plunderstorm is a "battle royale" style feature is hosted on a different server and uses different characters and abilities to regular World of Warcraft - in fact, it's pretty much a different game that happens to use WoW assets, but the rewards are available in the regular game. See Wowhead's Guide for more information.
