About These Birds
Polynesian Ground Dove
Small ground dove, 20–23 cm, with grey and brown plumage, dark reddish flight feathers, and white-tipped tail. Native to French Polynesia; extinct on many islands but survives in remnant populations on Moorea, Mopelia, and a few other atolls. Critically Endangered due to introduced rats, cats, and habitat loss.
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.
