This species is found in South-East Asia, particularly from the Nicobar islands to New Guinea, and as far north as the Philippines. It feeds on the forest floor,
and spends a great deal of time on the ground. They move about in flocks during the day and roost together at night. Their vocalization is a cooing sound.
