About These Birds
Palau Ground Dove
Small ground dove, 20–23 cm, with brown upperparts, a pale grey or whitish forehead and face, and buff-white underparts. Endemic to Palau in Micronesia, inhabiting dense forest and thickets. Terrestrial frugivore and granivore. Vulnerable due to the small island range and introduced predators.
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.
