Cocos buff-banded rail
The Cocos buff-banded rail, ''Gallirallus philippensis andrewsi'', is an endangered subspecies of the buff-banded rail endemic to the Cocos (Keeling) Islands, an Australian Offshore Territory in the central-eastern Indian Ocean.〔Commonwealth of Australia. (2005). ''National Recovery Plan for the Buff-banded Rail (Cocos (Keeling) Islands) Gallirallus philippensis andrewsi''. Department of the Environment and Heritage, Canberra. ISBN 0-642-55226-6〕 The local Cocos Malay name of the bird is ayam hutan ("Chicken of the Forest").〔(Bird stamps from Cocos Islands )〕
==Distribution and habitat==
This bird is now effectively limited to the 1.2 km² North Keeling Island. It is still occasionally reported from the 26 islands comprising the Southern Atoll of the Cocos (Keeling) Islands, where it was once common, but recent surveys have failed to find it. It is apparently extinct throughout the Southern Atoll apart from occasional visits by birds dispersing from North Keeling, which are unable to establish viable populations.〔Reid, Julian R.W.; & Hill, Brydie M (2005). ''Recent Surveys of the Cocos Buff-banded Rail (Gallirallus philippensis andrewsi)''. Report to the Australian Government Department of the Environment and Heritage. Centre for Resource and Environmental Studies, Australian National University: Canberra. ISBN 0-642-55193-6〕
On North Keeling the rails occupy all the limited ground habitats on the island, including the shore of the lagoon and the understorey vegetation of ''Pisonia'' forest and coconut palms.〔Garnett, Stephen T.; & Crowley, Gabriel M. (2000). ''The Action Plan for Australian Birds 2000''. Environment Australia: Canberra. ISBN 0-642-54683-5〕
Population size is estimated as 850-1000 birds, with a population density of 7-8 birds/ha.〔
