I believe this is probably a juvenile because of its yellow orbital and dull colors. Adults usually have a red orbital and brighter colors. This species is the largest member of the genus Coccyzus formerly included with other Lizard-Cuckoos in the genus Saurothera. The species may be divided into two groups; 1) Bahama and 2) Cuban. The latter is further divided into three subspecies of which this is the nominate found on the main island.
The Bahama group is sometimes split as a separate species, Bahama Lizard-cuckoo (Coccyzus bahamensis). This split is based on the controversial Tobias scoring system in which objective differences are supposedly scored consistently across taxa. The Bahama Lizard-cuckoo gets a score of "7" based on its duller color and slightly different tail pattern. This score puts it just over the line into being classified as a species under this scheme which has been adopted by Birdlife International and by HBW.
