described in 1829 by Karl Heineken. He recognised it as different from the now-extinct local form of the Madeiran wood pigeon, a subspecies of the common wood pigeon. This is a monotypic species, although in the past the Canarian Bolle's pigeon was sometimes regarded as a subspecies of the Trocaz pigeon. References External links BirdLife Species Factsheet.
