About These Birds
Luzon Bleeding-heart
Medium ground dove, 25–30 cm, with brown-grey upperparts and a dramatically blood-red breast patch on white underparts, resembling a chest wound. Endemic to Luzon in the Philippines.

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.
