Invisible rail
The invisible rail is endemic to the island of Halmahera in Northern Maluku, Indonesia. Its plumage is predominantly dark slate-grey, and the bare skin around its eyes, the long, thick bill and the legs are all bright red. The estimated population of 3,500–15,000 birds and the restricted range mean that it is classified as vulnerable by the International Union for Conservation of Nature.
About Invisible rail in brief
The invisible rail is endemic to the island of Halmahera in Northern Maluku, Indonesia. Its plumage is predominantly dark slate-grey, and the bare skin around its eyes, the long, thick bill and the legs are all bright red. Its call is a low drumming sound which is accompanied by wing-beating. The estimated population of 3,500–15,000 birds and the restricted range mean that it is classified as vulnerable by the International Union for Conservation of Nature. Habitat loss has occurred through the harvesting of sago and conversion of the wetlands to rice cultivation. The rail is eaten by local people, so the rail may be more adaptable to habitat changes than had been thought. The rails are a large and very widespread family, with nearly 150 species. They are small to medium-sized, terrestrial or wetland birds, and their short bodies are often flattened laterally to help them move through dense vegetation. This rail is related to the New Guinea flightless rail, Megacrex inepta and the chestnut rail, Eulabeornis castaneoventris, all three Australasian genera probably being derived from Amaurornis ancestors.
Of 53 extant or recently extinct taxa restricted to islands, 32 have lost the ability to fly. The invisible rail, first classified by English zoologist George Robert Gray in 1860, is the only member of the monotypic genus Habroptila. It is superficially similar to the purple swamphen porphyrio, which has recently been found in Halma Hera, but that species is larger, with a thick red bill and a red forehead shield. The sexes are identical in appearance; the plumage of the immature birds has not been described at the time of this article. The bird has a small spine at the bend of the wings, and has fledged immature birds at the age of two years old. The tukuk, tuk tuk, is a tuk-tuk, made by nature of the nature of nature; there is no overlap between the two species.
