Finnish White-tailed sea-eagles Haliaeetus albicilla in satellite tracking
The White-tailed sea-eagle working group within WWF Finland decided in early 2009 to start a joint project with the Finnish Museum of Natural History (University of Helsinki). The aim is to collect detailed data of the movements of White-tailed sea-eagles as they move around in our coastal areas through the year from the south-western archipelago and the Åland Islands to the corners of the Gulf of Bothnia and the Gulf of Finland. There are many ongoing plans to build wind farms in different parts of the Finnish sea coasts and archipelagos. Thus it is very important to collect exact data to point out areas that should be left untouched, being important for the protection of White-tailed eagles. The White-tailed sea-eagle working group has elected an advisory board for the satellite project. At this moment, its chair is Petteri Tolvanen from WWF (earlier adjunct professor Torsten Stjernberg from the Finnish Museum of Natural History). Professor Pertti Saurola is responsible for the information on this site.
- News–This section will updated always when some interesting or exceptional happens. The newest information about movements of these birds can be seen on the maps.
- Background–Includes information about the project, about the white-tailed eagle individual that are follwed and their home ranges.
- Older monitoring information
The newest maps will open by clicking the name of the individual. By clicking the symbol beneath the Google Earth will open with monitoring data (for viewing, Google Earth is required).
