Erythromachus

Description

The Rodrigues rail (Erythromachus leguati), also known as Leguat's gelinote or Leguat's rail, is an extinct species of the rail family that was endemic to the Mascarene island of Rodrigues, east of Madagascar in the Indian Ocean. It is generally kept in its own genus, Erythromachus, but has sometimes been assigned to the genus Aphanapteryx, along with its close relative the red rail (A. bonasia) of Mauritius; their relationship with other rails is unclear. The Rodrigues rail was about 35 cm (14 in) long and weighed at least 500 g (18 oz). It was described as having grey plumage, a red beak, red legs, and a naked red patch around the eye. The beak was long and decurved. It was flightless and fed on tortoise eggs. It was described as being attracted to red objects, which humans exploited while hunting it.
