ABR conducted ground-based nest searches for Spectacled Eiders on the Colville
Delta in areas that would likely receive some human disturbance from clean up workers
during the nesting season. ABR deployed groups of 4-8 researchers to thoroughly search
areas of ice roads and pads, Alaska Clean Seas equipment deployment sites, bridge
crossings, and around the CD-3 Pad and ice road from CD-3 to CD-2. Nest searching
was used to identify nest sites and thermistored eggs were used to record incubation.
Nest locations were immediately transmitted to environmental staff so that those areas
could be avoided by oilfield workers. In addition, ABR wrote a short letter report that
included a map of all Spectacled Eider locations and a list of their map coordinates, with
supplemental information on the fate of the nests. (2009–2011).
