サントメオリーブバト Columba thomensis

A large, very dark pigeon with a grayish head, a burgundy body with scattered small white spots, and a bright yellow bill and legs. Female is duller than the male. A scarce species found singly and in pairs in the canopy of primary and secondary forest, more frequently above 1300 meters of elevation; attends fruiting trees. Mostly quiet and inconspicuous, but gives a rolling, growling “crrr-crrow-rrrow-rrrow-rrrow” and other low-pitched pigeon-like cooing. Smaller Sao Tome Pigeon has a gray breast and an iridescent green nape and lacks Maroon Pigeon’s yellow feet and bill.
