A breeding male Chatham Island Taiko (Pterodroma magentae) was found recently dead of injuries by its burrow on 14 November 1996. Intraspecific fighting followed by sepsis of wounds seems the likely cause of death. All parts were preserved. Food items of Taiko include four squid species and one fish species. Its intestinal structure suggests a close relationship with the P. mollis group and P. macroptera. Measurements of bones indicate that most subfossil bones previously referred to this species were correctly identified.
