Chatham Islands Rail

Gallirallus modestus

Also known as Chatham Rail, Mangere Rail

Chatham Islands rails were small, flightless, nocturnal birds that navigated the dense ground cover and seabird burrows of the Chatham archipelago. Their slender, downcurved bills probed leaf litter and sandy soil for amphipods and insect larvae, filling an ecological niche distinct from their larger, sympatric relative, Dieffenbach's rail. Introduction of predatory domestic cats, rats, and extensive habitat burning by settlers decimated the fragile island populations by the end of the nineteenth century.
