South Island Adzebill

The South Island Adzebill is extinct and was known only in New Zealand. This skeleton is a composite specimen reconstructed from bones collected at Pyramid Valley Moa swamp in North Canterbury. They became extinct before the arrival of European explorers.

In life the Adzebills were massive  “crane-like” birds about 80 cm in length with a weight of 18 kg, making them about the size of small Moa, with which they were initially confused on their discovery.  The Adzebill had an enormous downward-curving and pointed bill, and strong legs. They were flightless and their colouration in life is not known.

The Adzebills were never as widespread as the Moa, but subjected to the same hunting pressure as all other large birds by the settling Polynesians and the predation of eggs and hatchlings by their accompanying kiore Polynesian rat and dogs.
