About These Birds
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.
Thick-billed Green-pigeon
Medium green-pigeon, 27–30 cm, named for its notably thick, curved bill adapted for crushing large fig seeds; male has a red bill base and maroon shoulder; female is green. Widespread in lowland and hill forest from the eastern Himalayas through Indochina to Sumatra, Borneo, and the Philippines. Frugivore of hard-seeded figs. Least Concern.
