The habitat of the gray-headed fruit pigeon are primary forests and old secondary forests. They are also found in forests with partial logging. The height distribution ranges from 600 to 1500 meters.

On Mindoro, gray-headed fruit pigeons occasionally use the same resting places as white-cheeked pigeons and large Mindoro fruit pigeons .
