These small doves were often quite tame allowing close approach. We found them to be abundant in settled areas around towns and villages where they are sometimes fed. They were introduced from Singapore in 1922 and have since spread to all the main islands. Sexes are similar but I believe this may be an adult male based on the wide separation of barring down the middle of its chest. Juveniles differ in having barring on the head. Their native range includes Southern Myanmar to Malaysia, Sumatra and Java. They were formerly lumped with the similar Peaceful Dove (G. placida) of Australia and New Guinea, and the Barred Dove (G. maugeus) of Indonesia, but now usually split into their own species. Peaceful and Barred Doves both differ in having barring extending all the way across the breast while Peaceful Doves also lack barring on the flanks. The three species have rather different vocalizations. Canon PowerShot SX60 HS.
