Hainan Partridge Arborophila ardens

Small game bird restricted to the tropical rainforests of southern Hainan Island, where it is the only forest-dwelling partridge. Body is brown above and gray below; head is black with a bright white ear patch and an orange collar. Unlikely to be confused with the only other game bird in its habitat, the Hainan Peacock Pheasant, which is far larger and gray all over. Shy and far more often heard than seen; ringing song is often heard at dawn.
