Hemiphaga is the genus containing two species of large pigeons from New Zealand.
There are two subspecies of New Zealand pigeon, Hemiphaga novaseelandiae: H. n. novaseelandiae of mainland New Zealand and the Norfolk pigeon (H. n. spadicea) of Norfolk Island, now extinct. The subspecies differed in their plumage colour and shape.[1]
In 2001, it was proposed that a third subspecies, H. n. chathamensis or the Chatham Island pigeon, was distinct enough to be raised to full species status as H. chathamensis.[2] This has since been accepted by most authorities.[3][4]
Taxonomy
[edit | edit source]The genus Hemiphaga was introduced by the French naturalist Charles Lucien Bonaparte in 1854 with the New Zealand pigeon (Hemiphaga novaeseelandiae) as the type species.[5] The name combines the Ancient Greek hēmi meaning "half-" or "small" with the end of the genus name Carpophaga introduced by Prideaux John Selby in 1835.[6]
The genus contains two species:[7]
