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.

Inhabits moist forest and plantation edges. Frugivore, feeding on figs and small berries. Endangered due to severe deforestation of its tiny island range.
