Large dark pigeon, entirely dark gray with contrasting white cap. Pink legs and pink bill with a pale tip. Adult has iridescent greenish scalloping on nape; difficult to see without a good view. Juvenile only shows faint pale forehead. A Caribbean species, common in coastal lowlands, especially mangroves. Restricted range in U.S.; found only in extreme southern Florida. 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. Listen for slow, repetitive cooing song, “woop-woop, woooop!”
