A partridge-like bird with an olive upper body, a mostly gray underside, and broad chestnut bands across the back and wings. Also note the white base to the undertail. Terrestrial, inhabiting forest in lowlands and hills, but most often seen by visiting specific beaches where they come to lay their eggs in the sand at night. The only patridge-like species in range with broad chestnut bands above. Vocalizations, mostly at night, include a moaning “kouw-kouw-kouw” and harsh, agitated “kek” calls.
