This standardized survey protocol allowed data collected by these diverse organizations to be stored together in a common digital archival system called the Alaska Swan Database, which is maintained by MBM-AK. Contributions to the database ranged from relatively small, localized surveys to the statewide quinquennial Alaska Trumpeter Swan Survey. Survey timing was either the spring nesting period or late summer...

It is produced from the code in wrangle_2022.R and contains information on on nest location, distance from transect, nest species, observer, and other covariates. For distance sampling analysis, it needs to be combined with the transect effort data in Effort_2022.csv. See the file wrangle_2022.R for details on quality control process.

Observations of sick and dead birds were collected during the nest distance sampling survey using the same distance sampling protocol so that an estimate of the number of bird carcasses could be produced. This is the main quality controlled data set for dead and sick birds recorded during the survey and used for the distance sampling analysis and population estimates.

The Spectacled Eider Recovery Plan ties recovery criteria to numbers of breeding pairs in each of the three nesting areas (YKD, North Slope, Arctic Russia). Lewis et al. (2019) compared ground-based nest abundance estimates to aerially estimated indicated breeding pairs to provide a means to assess recovery status from detection corrected aerial surveys. He reported that aerial crews detect 30-70% of nesting eider pairs, depending on nesting density; however, nest population estimates used in that study were derived from a...
