Exploring Prehistoric Seabird Use in the Bering Sea Erica Hill University of Alaska Southeast
Zooarchaeology of St. Lawrence Island reconstruct prehistoric subsistence Analysis and identification of animal remains from previously excavated sites
Taxa in SLI faunal assemblages • Walrus • Phoca spp. (seals) • Bearded seal • Polar bear • Canids • Seabirds (Alcidae) • Fish (probably ground fish) • Sea urchin
Why Seabirds? • Seabirds arrive in the spring bridge resource • Many seabirds and eggs can be harvested with • minimal risk and skill • Seabirds and eggs are predictable resources • Seabirds and eggs are clumpedresources
Alcidae(web-footed diving birds) • Puffins • Murres and Murrelets • Auks and Auklets • Guillemots
Alcidae(web-footed diving birds) • Usually associated with northern latitudes • Marine • Wing-propelled pursuit divers • Colonial nesters
Current work Correlating: • seabird colonies • walrus haulouts • human settlements
Conclusions • Breeding site fidelity in seabirds • Humans locating sites near colonies • Seabirds and their eggs were critical bridge resources
