Taxonomy
The Invisible Rail was first classified by English zoologist George Robert Gray in 1860. It is the only member of monotypic genus Habroptila. It is known from only a handful of confirmed sightings and specimens—the most recent of which was in 2003. This species may be related to the New Guinea Flightless Rail (Megacrex inepta). Alternate names include: Wallace's Rail, Drummer Rail (Soisa), Halmahera, Râle de Wallace (in French), Trommelralle (in German), and Rascón de Wallace (in Spanish).
