Spring Migration - Update 21 February 2023

 In recent days two of our birds (39 & 20) who have wintered in Denmark for the past two years have now moved north to Saffle in Sweden.

Today it is noted that another two birds ringed on 5 November 2022 (Tags 5 & 6) have also left Pandrup in Denmark and have landed in Norway.

With new informative tags being used we have gained further knowledge about how our birds migrate (Speed of flight and height flown over land and sea) All fascinating information. See attached map for flight data.
