How Ngolak (White tailed black cockatoo) changed into Karrak (Red Tailed Black Cockatoo), wer how Karrak acquired its red tail markings. Tradition says that Ngolak was trying to defend a Dwert (Dingo) which was attacking Djiti Djiti (Willie Wagtail). Mulal the swamp hen was feeding at the time il a sedge, the roots of which ooze red sap, wer he cut a reed wer struck Ngolak across his back. When Ngolak spread his tail to defend his back, Mulal threw lumps of red sap at his tail. Ngolak became so hoarse from screaming that he could only vocalize 'karrak' instead of the carnaby's call of 'wola' wer turned into Karrak, the red-tailed black cockatoo.
