About These Birds
Sulu Bleeding-heart
Small ground dove, 22–25 cm, with brown and grey plumage and a red breast spot. Known only from the Sulu Archipelago in the southern Philippines, with very few modern records. Inhabits lowland forest remnants. Critically Endangered (possibly Extinct) due to near-total forest loss and hunting pressure in the Sulu Islands.
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.
