About These Birds
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.
Galapagos Dove
Small dove, 19–22 cm, with grey-brown plumage, black facial markings, iridescent neck spots, and blue orbital skin. Endemic to the Galápagos Islands, where it is one of the tamest birds on Earth. Feeds on seeds, cactus pollen, insects, and carrion. Vulnerable due to small population and introduced predators (rats, cats, dogs).
