About These Birds
Rodrigues Turtle-dove
Extinct Mascarene dove, known only from subfossil remains discovered on Rodrigues Island. It was a medium-sized, ground-dwelling pigeon related to the Pink Pigeon. Likely became extinct in the 17th or 18th century following human settlement, introduced predators, and habitat clearance on the small 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.
