This work, identified by, is free of known copyright restrictions.
A color marking study was initiated on Kigigak island in the early 1990's to provide estimates of spectacled eider demographic parameters. These parameters were used to develop a population model for the species. Female spectacled eiders are captured and marked with a USFWS metal band, a uniquely coded tarsal band, and a uniquely coded nasal disc. These markers are used to identify the females in subsequent years and provide information about survival and recruitment which can be used in the population model. One method of trapping the female spectacled eiders is to use a bow-trap which is placed over the nest. This method has also been used to capture Pacific Black Brant, Emperor Geese, Cackling Geese, and Common Eiders. In this photo a bow trap has been placed over a goose nest.
