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.
Sumba Green-pigeon
Small-medium green-pigeon, 23–26 cm, entirely green with a yellowish wash on the breast; male has a small orange patch on the upper breast. Endemic to Sumba in the Lesser Sunda Islands. Inhabits forest and secondary growth. Frugivore of figs and small fruits. Least Concern.
