About These Birds
Negros Bleeding-heart
Medium ground dove, 25–28 cm, with brown upperparts and a distinct reddish breast spot, smaller than in Luzon Bleeding-heart. Endemic to Negros and Panay in the Philippines. Inhibits remnant lowland and hill forest. Critically Endangered; forest cover on Negros is near-exhausted, and the species may number fewer than 250 adults.
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.
