Cuban Macaw Ara tricolor in the Upper Pleistocene of Western Cuba

The Cuban macaw Ara tricolor (Bechstein, 1811) is an extinct species of large parrots. Its historical distribution and ecology are poorly understood. To date, only three late Quaternary paleontological and one archeozoological (17th-18th centuries) finds of the species have been described from central Cuba. A new (fourth) fossil find of the Cuban macaw is described and is a fragmentary carpometacarpus from Upper Pleistocene layers of the El Abrón Cave in the Pinar del Río province. The find provides the first documented evidence of the species from the western part of Cuba. The associated fauna indicates that the Cuban macaw lived in mosaic, semi-open marshy landscapes, which were probably similar to those in the vicinity of Ciénaga de Zapata in modern times.
