Beschrijving
This study examined the migration routes and spatial distribution of King Eiders breeding in northern Alaska throughout the annual cycle. Satellite transmitters provided information on migration timing, migration distances, location of important molt, winter, and staging areas, migratory connectivity between those areas, and estimates of annual survival for adult and juvenile King Eiders. meer
King Eiders are large sea ducks that nest in Arctic ecosystems around the world and migrate and winter at sea. Since 2002, the University of Alaska Fairbanks has tracked the migration and movements of King Eiders from breeding grounds in northern Alaska. This dataset includes all the locations provided by satellite-tracked King Eiders between June 2002 and December 2008. King Eiders migrated from breeding grounds in northern Alaska to winter regions in the Bering Sea. Females returned to breeding grounds in Alaska, whereas males dispersed over 50% of the species global range in the summer after capture. The authors and field assistants captured adult and juvenile King Eiders with mist nets on breeding grounds in northern Alaska and equipped each bird with an implanted satellite transmitter (PTT 100, Microwave Telemetry Inc.). Satellite transmitters provided locations every 2-7 days for a time period of 10-20 months per individual. We used a filter program (PC-SAS Argos Filter v7.02, David Douglas, USGS Science Center) to remove implausible locations, and retained one location per duty cycle. The filter algorithm flags implausible locations based on two different filtering methods:
