The Madagascar forest rail (Mentocrex kioloides), also known as the Madagascar wood rail or the kioloides rail, is a species of bird in the family Sarothruridae. It is endemic to forests, often in wet areas, in northern and eastern Madagascar. The Madagascar forest rail is a secretive and shy species, often showing elusive behavior, such as running away from the slightest disturbances. This has contributed to a lack of study on this species; a reason why it is not that well known.[2]
This species was formerly placed in the genus Canirallus together with Tsingy forest rail and the grey-throated rail. A molecular genetic study published in 2019 found that the grey-throated rail is not closely related to the forest rails. The forest rails were therefore moved to the resurrected genus Mentocrex.[3][4]
