Rock pigeon

Columba livia atlantis | Rock dove 

The rock dove (or rock pigeon) is a sub-species of the domestic pigeon and is most probably derived from feral pigeons. This subspecies is found throughout Macaronesia (the Azores as well as Madeira, the Canary Islands and Cape Verde). Their typical plumage is like that of other subspecies: grey with black stripes on the wings, black wingtips, and a glossy green and purple chest and neck. However, in this subspecies there is more colour variation, such as a checkered dorsal plumage. The beak is small, think and black with some white at the base. Rock doves are most abundant in coastal areas with cliffs. In the Azores the largest populations can be found on the islands of São Jorge, Terceira and Flores. Nesting occurs between March and July. This species is classified as "common breeding" in the Azores.
