This dark purplish grey pigeon is unmistakable with its chess-board like pattern on the neck.  Vinous underparts and broad tail.  Sexes alike.  Juvenile is duller and has only a hint of the chess-board on the neck.  A scarce forest pigeon of montane forests and nearby well-wooded habitats in the higher hills, occasionally descending to the lower hills.  Usually shy, lives in pairs or small groups.
