LOS CÓNDORES (CICONIIFORMES, VULTURIDAE) DE LA REGIÓN PAMPEANA DE LA ARGENTINA DURANTE EL CENOZOICO TARDÍO: DISTRIBUCIÓN, INTERACCIONES y EXTINCIONES
AbstractThe fossil record of condors from the Upper Cenozoic of the Pampean region is rich and diverse. The declination, retraction in range and extinction of many taxa of "pampean" condors during Pliocene-Pleistocene times were probably related to both climatic-environmental changes and reduction or loss of food supplies. The influence of the availability of food supplies was remarkable in the late Pleistocene because of the massive extinction of megaherbivorous mammals, the carcasses of which were the condor's main food source. Competition between condors and phorusrhacoid birds is proposed in light of their scavenging habits.
