Processing Activities and Differentiation of Bird Utilization During the Late Holocene in the Beagle Channel Region (Southern South America)

Abstract

ABSTRACTRecent research into prehistoric subsistence among the sea nomad societies of the Beagle Channel region of southern South America have shown that there were temporal changes in the utilization of animal resources between the Middle and the Late Holocene. A relative increase in the utilization of fish and birds has been noted in the Late Holocene, together with changes in the selection of bird and fish taxa. The most important change was the appearance of sites in high topographic locations where special activities were recorded that were related to the intensive exploitation of Phalacrocoracidae and the increase in the utilization of Procellariiformes.In this paper, we examine the characteristics of these later assemblages in order to explore possible explanations for the changes in the use of birds. The cut marks on the bones were distinguished in order to differentiate the activities involved. The results indicate that in the Late Holocene there was no differential pattern of cormorant butchering between those sites where special tasks took place and general activity sites. It was also shown that the increase in Procellariiformes was linked mainly to subsistence rather than technological factors. Copyright © 2013 John Wiley & Sons, Ltd.
