About These Birds
Picui Ground Dove
Small dove, 18–22 cm, pale grey with white wing stripe and dark-tipped tail. Widespread in open and semi-open habitats from Brazil and Bolivia south to central Argentina and Uruguay. Granivore of seeds. Common in agricultural areas and grasslands. 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.
