Eyes on Eiders Header
       

Every step is an act of balance in a vast land full of ponds, rivers, and streams where more than half the landscape is water. There are no roads and your tent could be the highest point on the horizon. Trekking though the swampy tundra of the Yukon-Kuskokwim Delta (Y-K Delta), scientists are on the lookout for nests. Counting every species they encounter, one bird eludes them all: the Steller's eider. This mysterious bird is a rare sight for researchers across Alaska. Surprisingly, one of the best places to observe these birds in Alaska is at a facility that is located hundreds of miles from their natural habitat.

Watch the video for a glimpse into the strange lengths that scientists are going to in order to learn as much as possible about the elusive Steller's eider. Can you guess what the researchers are doing - and why?

Why are scientists going to such great extents to learn more about the Steller’s eider? The number of Steller's eiders in the wild are declining. While two breeding populations exist in northern Russia, the breeding population of Steller’s eiders in Alaska has all but vanished and is now classified as Threatened under the Endangered Species Act.

No one knows why these birds started disappearing in the 1970's. Scientists have proposed a few possible explanations, such as lead poisoning from ingestion of spent lead shot; increased predation from gulls, foxes and ravens; and changes in the coastal environment. As temperatures warm and sea levels rise near the eiders' preferred habitats, will the few remaining pairs of birds continue to be successful nesting in Alaska?

Concerned for the Alaskan population, scientists collected Steller’s eider eggs from Barrow, Alaska in an effort to prevent a complete disappearance of breeding eiders. With these eggs, the scientists have created a captive-breeding “reservoir” population. This breeding population resides at the Alaska SeaLife Center in Seward, Alaska, where researchers and aviculturists have the skills to keep the birds healthy while they learn more about this rare species.

Video Transcript

Dr. Tuula Hollmen has been studying Steller's eiders at the Alaska SeaLife Center since 2001. Her project allows scientists to keep their eyes on eiders, to observe and learn about a bird rarely seen nesting in the wild.
