CD-3 Spectacled Eider Monitoring Study

CD-3 Spectacled Eider Monitoring Study

ABR conducted a 3-year study of disturbance to nesting Spectacled Eiders at CD-3,
a new well pad on the Colville Delta constructed in 2004 and 2005. Four years of preconstruction
data on nesting were used as baseline. Spectacled Eider pre-nesting and
nesting distribution relative to CD-3 was evaluated over a period of pre-construction
years and 3 years during construction and operation. Nest searching was used to
identify nest sites, thermistored eggs were used to record incubation, and time-lapse
photography was used to identify predators and reactions to disturbance. The effects
of construction and flight activity were evaluated through changes in nest distribution,
nesting success (daily survival rates) and changes in nesting behavior. (2005–2007).
