sentences:  The estimated population of 3,500–15,000 birds and the restricted range mean that the invisible rail is classified as vulnerable by the International Union for Conservation of Nature (IUCN).Habitat loss has occurred through the harvesting of sago and conversion of the wetlands to rice cultivation, and the rail is eaten by local people.The described nest was in an area frequented by local villagers, so the rail may be more adaptable to habitat changes than had been thought.
