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.
Yellow-vented Green-pigeon
Yellow-vented Green-pigeon (Treron seimundi), 28 cm. Green above with a grey head; diagnostic bright yellow vent contrasts with pale green underparts. Resident in lowland and foothill forest of the Thai-Malay Peninsula and Sumatra. Frugivore foraging in fig-laden canopy. Uncommon; sensitive to lowland forest loss.
