Gallirallus

Ashore, penguins are prey to a variety of species, such as leopards in South Africa, and Weka (Gallirallus australis) in New Zealand, whilst introduced species such as stoats, rats and feral cats will feed on nesting birds.

The Okinawa rail (Gallirallus okinawae, EN) is represented by a single population in the Yambaro Forest on northern Okinawa.

Other birds with no close relatives beyond New Zealand found in the area include: blue duck Hymenolaimus malacorhynchos, wrybill Anarhynchus frontalis and western weka Gallirallus australis.

Feral cattle, sheep, pigs, and possums need to be controlled in order to prevent further damage to native vegetation, and predator control programs need to be continued to keep rats, mice, hedgehogs, cats, dogs, and wekas (Gallirallus spp.) in check.

Extant endemics on Rakiura and its offshore islets include subspecies of southern robin (Petroica australis rakiura), weka (Gallirallus australis scotti), and fernbird (Bowdleria punctata stewartiana), as well as a leaf-veined slug, a Paryphanta spp., and the harlequin gecko (Hoplodactylus nebulosis).

Two species from Caledonia that have not been recorded reliably for many years, include the New Caledonian lorikeet (Charmosyna diadema, CR), last recorded in 1913, and the New Caledonia rail (Gallirallus lafresnayanus, CR), not reliably reported since the early 20th century.

In May 2004, a possibly new species of rail Gallirallus was observed on Calayan island in the Babuyan islands, northern Philippines.
