About These Birds
Santa Cruz Ground Dove
Small ground dove, 20–23 cm, with brown upperparts, a grey head, and pale buff underparts. Known from the Santa Cruz Islands (Solomon Islands) and Espíritu Santo (Vanuatu). Inhabits dense lowland forest floor. Terrestrial frugivore. Critically Endangered; very few recent records and significant forest loss throughout its range.
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.
