RESUMO

The dynamics of the taxonomic diversity of the birds of Cuba during the Late Pleistocene-Holocene is assessed for the first time using material from El Abrón Cave in the western part of the island. The Upper Pleistocene beds of the locality are characterized by a rich taxonomic diversity of birds, including an abundance of waterbirds and open-landscape inhabitants. For the Holocene, a general decrease in taxonomic diversity and a significant increase in the number of remains belonging to representatives of forest faunas (Picidae) are recorded. Our data indicate a significant transformation of landscapes of western Cuba and the faunistic associations of birds at the end of the Quaternary, which is consistent with paleoclimatic data.
