 The difficult habitat and retiring nature of the invisible rail mean that information on its lifestyle is sparse , and there are few confirmed sightings . Recorded food items include sago shoots and insects . It also feeds at cut sago plants , although it is unclear whether it is eating the decaying plant or searching for other edible items . It swallows small stones , as do all rails , to help break up its food in the gizzard .
