About These Birds
Brown-capped Emerald Dove
Small dove, 23–26 cm, with iridescent emerald-green upperparts, a brown crown (not grey), and a longer bill than the Grey-capped Emerald Dove.

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.
