Eider Surveys (1994-2023)

Spectacled Eiders and Steller's Eiders occur on the Colville River Delta and are listed by the U.S. Fish and Wildlife Service (USFWS) as threatened species under the Endangered Species Act. Oil field operations requires documentation of the presence or absence of eider nests prior to initiating off-pad activities during the nesting season. Results for nesting surveys are provided in this record.

Spectacled Eiders (Somateria fisheri) population status on the North Slope is being monitored in support of the population recovery effort. Annual surveys for Spectacled Eiders began in the Kuparuk Oilfield in 1993 and have included searches for King Eiders (Somateria spectabilis) which nest in similar habitats and are frequently encountered while searching for Spectacled Eiders. Stellar's Eider is rare on the Colville delta and nests primarily near Barrow, although their historic range included all of the Arctic Coastal Plain in Alaska.

King Eider is an important subsistence species for local Iñupiaq people and in 2020, at the request of the NSB, CPAI began conducting a multiyear study focused on King Eiders to address possible effects of GMT and Willow Project development on their breeding biology and behavior by comparing pre-construction, construction, and postconstruction periods. These studies are provided in this record.

A link to reports for avian monitoring in the vicinity of Alpine area since 1998 is also provided below.
