About These Birds
Tanna Ground Dove
Small ground dove, 19–22 cm, ferruginous-rufous overall with a grey head and pale underparts. Extinct; formerly occurred on Tanna Island in Vanuatu. Last collected in the 19th century; became extinct through hunting and habitat loss following colonial settlement of the island.
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.
