The Eupetidae familly consists of just one species the Rail-Babbler recently shown by DNA sequencing to warrant full family status.

The Rail-babbler or Malaysian Rail-babbler Eupetes macrocerus is a strange, rail-like, brown and pied inhabitant of the floor of primary forest in the Malay Peninsula and Sumatra (the nominate subspecies macrocerus), as well as Borneo (ssp. borneensis). It is distantly related to African crow-like birds. Its population has greatly decreased because much of the lowland primary forest has been cut, and secondary forests usually have too dense a bottom vegetation or do not offer enough shade to be favourable for the species. However, it is locally still common in logged forest or on hill-forest on slopes, and probably not in immediate danger of extinction. The species is poorly known and rarely seen, in no small part due to its shyness.

It is a medium-sized, fairly slender passerine, about 28cm to 30cm in length, and weighing 66g to 72g. It has a long thin neck, long black bill, long legs and a long tail. The plumage is mainly brown with a more reddish forehead, crown and throat. It has a long, black eyestripe extending from the bill to the side of the neck and a broad, white supercilium above it. There is a strip of bare, blue skin on the side of the neck which can be seen when the bird calls. Juvenile birds are similar to the adult but have duller head stripes, a whitish throat and greyer belly.

It has a long, monotonous whistling call. When agitated, it gives a series of frog-like notes.

It is found on the Malay Peninsula in southern Thailand and Peninsular Malaysia and in the Greater Sundas on Sumatra, Borneo and the Natuna Islands. It mainly occurs in tall, lowland forests and also in swamps and heath forest. It sometimes occurs in lower montane forests up to about 1,060m in Peninsular Malaysia and 900m in Sumatra and Borneo. It is believed to be declining due to loss and degradation of the forest and is classed as near threatened.

It is a shy and secretive bird, which lives on the forest floor. It walks like a rail, jerking its head in the manner of a chicken, and it prefers to run rather than fly when disturbed. It feeds mainly on insects, including cicadas, and beetles as well as spiders and worms. When feeding it will dash after prey items.

Little is known about its breeding habits. The eggs are laid around January and February and fledgeling have been seen in June. The nest has been described as being placed near the ground on a pile of dead leaves among the stalks of a plant around 30cm from the ground. It is made of plant fibres and is a cup shape. The clutch is two white unmarked eggs, nothing else is known.
