Bird ringing at the northernmost station in Sweden

Together with naturum Abisko, CIRC participates in the National program, Constant Effort Sites (CES) which aims at monitoring the presence of demographics (that is age and sex) of locally breeding birds, thus following the state of the environment and detecting impacts from possible environmental changes. The project first started in the beginning of the 1980s in the UK and is currently operating at different stations all over Europe and the World. The station in Abisko is the northernmost station in Sweden. The most abundant birds CIRC researchers ring during the summer are willow warbler, blue throat, reed bunting, brambling, fieldfare, redwing and a few others.
