In the Galapagos these habitats are generally found on islands with higher elevations (particularly on the islands of Santiago, Santa Cruz and Sierra Negra), and the rails are commonest higher up. They feed on invertebrates, mostly snails, isopods, dragonflies, bugs, ants, also taking berries and some seeds. They feed during the day, moving along the ground tossing leaves and investigating the leaf litter.[citation needed]
