Late May - satellite tagged long-tailed ducks are trying to get as far north and east as ice allows!

Migrating common eiders have reached their destination in the northern Baltic in April, while most of other ducks are parking in the Estonian and Latvian waters

Nine common eiders have been equipped with GPS-activity data loggers in February and March 2010

In January 2010, 10 long-tailed ducks, 5 tufted ducks and 2 common scoters have been implanted with satellite transmitters.

One eider male tagged in March 2009 has been shot by a hunter at Langeland on February 8 after succesful transmission for 11 months.

We deployed 10 more satellite transmitters on common eiders in late October 2009.

Welcome to sea duck telemetry page!

This webpage is dedicated to presentation of bird telemetry studies conducted in connection with planning and construction a fixed link between Denmark and Germany over the Fehmarnbelt. We are currently collecting baseline information prior construction of the link. Telemetry offers tools to collect data on bird habitat use, behaviour, short- and long-range movements.

We started with tracking common eiders in spring 2009. Then we used GPS telemetry to study habitat use of moulting mute swans in Rødsand Lagoon in August 2009. In winter 2009/2010 we deployed more satellite and VHF radio transmitters on wintering eiders, tufted ducks, long-tailed ducks and common scoters.
