About These Birds
Sapphire Quail-Dove
Small, 24–27 cm, quail-dove with brilliant sapphire-blue iridescence on the crown and nape, contrasting with rufous-brown upperparts and a white facial stripe. Inhabits lowland and foothill humid forest from eastern Colombia and Peru to the Guianas and northern Brazil. Terrestrial forager of seeds. Least Concern.
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.
