About These Birds
Sao Tome Bronze-naped Pigeon
Sao Tome endemic pigeon, 26–28 cm, dark slaty-brown with an iridescent bronze-green nape patch and pale underparts. Restricted to the forests of São Tomé Island in the Gulf of Guinea. Frugivorous, foraging in the forest canopy for fruits and berries. Threatened by habitat loss; classified as Near Threatened.
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.
