About These Birds
Mindanao Bleeding-heart
Medium ground dove, 25–30 cm, with brown upperparts, a blood-red breast patch, and a distinctive crest of long dark hackles on the hindneck. Endemic to Mindanao and adjacent Philippine islands. Inhabits primary lowland and hill forest floor. Terrestrial frugivore and granivore. Vulnerable due to ongoing deforestation.
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.
