Large dark pigeon, entirely dark gray with contrasting white cap. Pink bill and legs. Adult has iridescent greenish scalloping on nape; difficult to see without a good view. Juvenile shows only faint pale forehead. Mainly a Caribbean species, restricted range in US; found in forested areas in extreme southern Florida, especially mangroves. Tends to be quite shy; most often seen in pairs or small flocks, often in flight. White cap and pink bill separates from all-dark morph of Rock Pigeon. Coos like a Mourning Dove but with slightly different pattern.
