33. New Caledonian Rail

Gallirallus lafresnayanus

About

The New Caledonian Rail has not been recorded since 1890, and is believed to have a total population size of below 50 mature individuals, if not extinct.

There have been reports that this species may survive in small numbers in New Caledonia near Mt Panié in the north and the headwaters of Rivière Blanche in the south in the 1960s, suggesting this species can remain in largely inaccessible montane forests. This species is part of the Gallirallus genus which diverged from all other genera in the Rallidae family 9.89 million years ago. This species is likely to have been made extinct from predation by cats, pigs and rats that were introduced to the island. There are also historical records of the birds being caught by hunting dogs. This species may be benefiting from the conservation actions for Rhynochetos jubatus, as this has led to the control of introduced mammalian predators. The only measures taking place are in the Rivière Bleue Park, where the occurrence of the rail is very unlikely.
