30 Years Later: Are Spectacled Eiders still a Mystery?

A presentation for Friends of Alaska National Wildlife Refuges by Dan Rizzolo, Endangered Species Biologist, USFWS (and ASI Board Member!)

Spectacled eiders were in rapid decline in the Yukon Delta National Wildlife Refuge in 1993 when they received the protection of the Endangered Species Act by being listed as a Threatened species. They were a mystery then. Western science knew very little about this sea duck species with the spectacled plumage. We knew they made their nests in the coastal tundra along the Bering Sea and Arctic coasts of Alaska and Siberia, but not where they molted their feathers or spent the winter. How many were there? What did they eat? And, importantly, why were they in such rapid decline? In the 30 years since they were listed, we have learned much about this tough duck that winters among the pack ice in the Bering Sea. In this 50th anniversary year of the Endangered Species Act, join us for Dan’s review of what has been learned since listing, including how spectacled eiders are responding  to changes in sea ice in the Bering Sea. But knowledge does not always bring recovery and with ongoing anthropogenic climate change, the spectacled eider continues to face an uncertain future.
