Justification:
This species is known from New Zealand's North Island, but it was last recorded in 1907 and is now Extinct. Habitat loss, hunting and disease have all been implicated in its decline.

Geographic Range [top]

Range Description: Heteralocha acutirostris was endemic to the southern portion of the North Island, New Zealand. It was intensively studied by Buller in the second half of the 19th century (Phillipps 1963), and is known from numerous specimens (Greenway 1967), but declined to extinction around the turn of the century with the last confirmed record being in 1907 (Myers 1923).
