Regional Differences

Ornithologists recognize three subspecies: sula of the Caribbean and Atlantic, websteri in the tropical eastern Pacific Ocean, and rubripes in the remainder of the species’ wide range. All subspecies show multiple color morphs. However, websteri in the Galapagos is the only one with a black-tailed white morph.
