Gallirallus sp. nov. ‘Norfolk Island’

Norfolk Island rail

 

 

Taxonomy & Nomenclature

The species has not been given a scientific name, so the informal name appended gives its geographic origin. Its remains have been described as larger than those of G. philippensis and was potentially flightless (Meredith, 1985, 1991), with an estimated weight of ?250gm compared to 170gm for the latter (Holdaway & Anderson, 2001:94).

 

Conservation Status

Extinct

Last record: subfossil (Meredith, 1985, 1991) (confirmed); c.1790 watercolour (Hunter & Calaby, 1989) (unconfirmed)

 

Subfossil remains were reported by (Meredith, 1985, 1991). Two watercolours, the original by John Hunter in c.1790 and a later 'copy' made pre-1801, have been hypothesised to represent this extinct species (e.g. Holdaway & Anderson, 2001:94).
