Gallirallus is a genus of rails that live in the Australasian-Pacific region. The genus is characterised by an ability to colonise relatively small and isolated islands and thereafter to evolve flightless forms, many of which became extinct following Polynesian settlement.
Description
Many of the rails, including the well-known weka of New Zealand, are flightless or nearly so. Many of the resultant flightless island endemics became extinct after the arrival of humans, which hunted these birds for food, introduced novel predators like rats, dogs or pigs, and upset the local ecosystems. A common Polynesian name of these rails, mainly relatives of G. philippensis, is veka/weka (in English, this name is generally limited to Gallirallus australis).
On the other hand, Gallirallus species are (with the exception of the weka) notoriously retiring and shy birds with often drab coloration.
Living and recently extinct species
In the online list maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC), the genus contains two species:[1]
| Image | Scientific name | Common Name | Distribution |
|---|---|---|---|
 |
Weka | Gallirallus australis | New Zealand |
| Calayan rail | Gallirallus calayanensis | Calayan Island in the Philippines. |
These species are placed by BirdLife International and IUCN in the separate genus Hypotaenidia but are still considered part of Gallirallus by The Clements Checklist of Birds of the World/eBird:

A similar bird was found to live on nearby Vava‘u in 1793. Given that G. vekamatolu was flightless, this may just as well represent a related species.
