Regional Differences
Three subspecies found in Florida, Mexico, the Caribbean, and most of Central America are very similar to each other. A fourth subspecies that occurs from eastern Panama through South America, known as guarana, is smaller, darker, and has white markings only on the neck. Some authors have considered guarana to be a separate species.
