About These Birds
Purple-winged Ground Dove
Small dove, 18–21 cm; male dark blue with purple wing bars; female brown with rufous wing bars. Tied to Atlantic Forest bamboo in southeastern Brazil, Paraguay, and northeastern Argentina. Nomadic, appearing in flocks only during bamboo seeding. Endangered due to extensive Atlantic Forest loss; rarely recorded in recent decades.
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.
