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.
Grey-cheeked Green-pigeon
Small-medium green-pigeon, 25–27 cm; male has a grey head, grey cheeks, and green body with a yellow-green breast; female is green with grey cheeks. Found in lowland and hill forest from Sulawesi through Maluku to the Lesser Sundas and Philippines. Frugivore of figs and small berries. Least Concern.
