The gwayo bird was an animal native to the planet Sakiya. The native sentient species, the Sakiyans, hunted for gwayo bird eggs. The process involved simply tracking the birds to their nests. When the Sakiyan bounty hunter Djas Puhr was hunting Ghostling children in Gardulla the Hutt's pleasure garden on the planet Tatooine, he realized that he could similarly follow the movements of the Ghostlings' Wistie allies to locate the children.
