In 1964, rats arrived on Taukihepa, a muttonbird island south-west of Stewart Island. The South Island snipe was already confined to this one location after being eliminated everywhere else. Two birds were caught in a last rescue attempt. Neither bred in captivity. The species was gone within a few years of the rats coming ashore. Tutukiwi was, like all New Zealand snipe, a bird that had abandoned the coastal mudflats normally associated with waders and moved into the forest interior. It probed leaf litter and soil for earthworms and invertebrates with a long, sensitive bill, relying on touch rather than vision, in much the same manner as a kiwi. Compared to most waders it was slow-moving and sedentary, perfectly adapted to an environment without mammalian ground predators. That adaptation was excellent for everything except rats, which are neither slow nor sedentary, and which arrived on Taukihepa with no particular agenda beyond eating whatever was available. Its prehistoric range covered the South Island and Stewart Island, with subfossil remains indicating abundance far beyond its final refuge. Human arrival compressed that range steadily before European settlement added further pressure. By the time detailed records were kept, the species was restricted to a handful of offshore islands. Taukihepa, used by Māori for centuries as a tītī harvesting site, held the last viable population, though nobody knew at the time that it was also the last anywhere. Muttonbirders knew the snipe's aerial display as the hakawai: an unseen, descending call given at night during courtship, the bird invisible against the dark sky. Māori understood this as the voice of a spirit bird, powerful and without physical form. It was not supernatural. It was a small wader performing a display flight in complete darkness, the sound arriving before any visual impression was possible. The hakawai over Taukihepa stopped in the late 1960s, noticed first as an absence rather than an event. What remains is the record of the attempt. Don Merton and Wildlife Service staff on the island in 1964, catching two birds, shipping them out, watching them fail to breed, and documenting what came after. The South Island snipe is New Zealand's most recent documented bird extinction. It did not go gradually. It went in the years following a ship arriving with rats that had nowhere particular to be, on an island whose isolation, the only protection the snipe had left, became the last thing it had to lose.
