 While the weight is not recorded, comparison with related species gives an estimate of 350 grams on average.The colour pattern, unusual for a "Columba" pigeon, probably represents convergent evolution towards the PIP, and possibly even a case of Müllerian mimicry, the anti-predator attribute being the PIP's habit to aggregate in large flocks which makes it harder for predators to pick out individual birds, and enables the much rarer silvery pigeon to share this advantage.This species was recorded during the late 19th and early 20th century from offshore islands of the Natuna Sea (west of Borneo) and west of Sumatra, Indonesia, and on the adjacent mainland.
