About These Birds
Grenada Dove
Medium dove, 25–28 cm, brown above with a pale grey head and pinkish-white underparts. Endemic to Grenada, Lesser Antilles, in dry and moist lowland forest and scrub. Terrestrial forager of seeds and fruits. Critically Endangered; estimated fewer than 150 individuals due to habitat loss and introduced predators.
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.
