About These Birds
Mariana Fruit-dove
Mariana Fruit-dove (Ptilinopus roseicapilla), 23 cm. Vivid green body, rose-red cap and white to pale yellow underparts; endemic to the Mariana Islands. Inhabits native limestone forest. Frugivore.

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.
