Aplonis fusca (Gould)

Norfolk Starling (Aplonis fusca)

The Norfolk Starling, aka. Tasman Starling, was restricted to Norfolk Island.

The species reached a size of 20 cm; it was greyish brown colored, with the males having some metallic glossy green feathers on the head.

The Norfolk Starling disappeared due to a combination of several factors, including competition from introduced European Starlings and thrushes, overhunting and destruction of their habitats through agricultural clearings.

The species was apparently last seen in 1923.

Ninox novaeseelandiae ssp. undulata (Latham)

Norfolk Island Boobook (Ninox novaeseelandiae ssp. undulata)

The Norfolk Island Boobook was described in 1801; it was endemic to Norfolk Island, where it inhabited the subtropical rainforests.

The taxon disappeared after the European settlers begun to clear the forests.

The population was reduced to a last surviving bird in 1986, a female bird named Miamiti, which died in 1996.

***

This female mated with a male boobook of the nominate race that had been introduced to Norfolk Island and produced some offspring, which again has given rise to the small population of hybrid boobooks that now inhabit this island.

Hemiphaga spadicea (Latham)

Norfolk Island Pigeon (Hemiphaga spadicea)

The Norfolk Island Pigeon is still often regarded to as a subspecies of the New Zealand Pigeon (Hemiphaga novaeseelandiae (Gmelin)) but clearly constitutes a distinct species.

The species reached a size of 50 cm and differed from the New Zealand Pigeon mainly by the coloration of its wings, which were grey instead of green.

The Norfolk Island Pigeon was apparently last recorded in 1838 and appears to have been gone just by one year later, the reasons for its extinction are overhunting but also predation by introduced mammals, especially cats.

Nestor productus (Gould)

Norfolk Island Kaka (Nestor productus)

The Norfolk Island Kaka was described in 1836, it was restricted to the Norfolk Islands, where it was the largest parrot species.

The species reached a size of about 33 cm, it was rather variable but was mainly very bright yellow and brick red colored on the underside, while the upper side was mainly dark brown. The beak was very much elongated and several specimens show strange bill deformities.

The Norfolk Island Kaka disappeared due to overhunting.
