The island belongs to the municipal of Hvaler, a group of small islands outside the town of Fredrikstad. The first scientifically ringing of birds took place already in 1955. The station-building in 1989, drawn by Jorun Pettersen. This is the same house the author Johan Borgen used as a summer house between 1955 and 1969. Have a look at some recent reports.
Old reports are still available.
After I finally got my video equipment working, plenty of short videos of variable quality should start to show up here. The best year so far was 1988 with over 6500 birds ringed. The numbers of birds ringed are heavily influenced by how well we are able to man the station. In normal years we spend between 60 and 80 days, mostly weekends, resulting in about 3000 ringed birds. The figures for 1995 .
