About These Birds
Marquesas Ground Dove
Small ground dove, 19–21 cm, with warm rufous-brown plumage and paler underparts. Formerly occurred across the Marquesas Islands of French Polynesia. Extinct; last confirmed in the early 20th century; eliminated by introduced rats, cats, and habitat loss throughout the archipelago.
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.
