Standing about 80 centimetres tall, the North Island adzebill (Aptornis otidiformis) was a large flightless bird with a down-curved bill. The size of the bill suggests that the bird was a predator, possibly eating large invertebrates, lizards, tuatara and nesting birds.
Fossils have been found at a few sites around the North Island, in open country. The birds are thought to have died out soon after human settlement, probably because they were hunted.
