The Pincoya storm petrel (Oceanites pincoyae) is a sea bird of the storm petrel family. The specific name commemorates the Pincoya, a female water spirit of the Chilote mythology. After being first brought to the attention of the world from photographs taken by Seamus Enright and Michael O'Keeffe in 2009 this species was finally formally discovered and examined in 2011 and scientifically described in 2013.
