About These Birds
Silvery Pigeon
Silvery Pigeon (Columba argentina) — 36–40 cm. Pale silver-grey overall; darker back; pinkish bill; no distinctive markings. Inhabits small forested islands and coastal areas of Indonesia (Sumatra, Borneo region). Frugivore. Endangered; known from very few records and facing severe pressure from deforestation and hunting.
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
