About These Birds
Blue Ground Dove
Small dove, 18–21 cm; male is pale blue-grey with dark wing spots; female is warm brown with purple-chestnut wing bars. Inhabits forest edge, secondary growth, and thickets from Mexico to Bolivia and southeastern Brazil, with a preference for bamboo-seeding events. Granivore of bamboo seeds. Nomadic following bamboo flowering cycles. 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.
