Square kilometre (US spelling: Square kilometer), symbol km², is an SI unit of surface area. ...
In autumns 2001 and 2002 three samples of long-distance passerine migrants were trapped on Christiansø and displaced to Endelave where the birds were caged and tested for several days/weeks within homogeneous magnetic fields where magnetic N was deflected W (4 fields) or E (another 4 fields).
The main purpose of the experiments was to investigate the hypothesis of the Wiltschkos and others that the magnetic compass in the sunset/early night phase calibrated the stellar compass for the rest of the night.
The results are presented in the document Dron06b (submitted) and again no signs of calibration in the sunset/early night phase of the magnetic- or the sunset compass were observed.
