The Puerto Rican Amazon (Amazona vittata), also known as the Puerto Rican Parrot or Iguaca, is enemic to the archipelago of Puerto Rico belonging to the neotropical genus Amazona. Measuring 28–30 cm (11–12 in), the Puerto Rican Amazon is a predominantly green parrot with a red forehead and white rings around the eyes. Two subspecies have been described, although there are doubts over the distinctiveness of the form gracilipes from Culebra Island, extinct since 1912. Its closest relatives are believed to be the Jamaican Black-billed Amazon (Amazona agilis) and the Hispaniolan Amazon (Amazona ventralis).
