Résumé :	Results of further investigations (DEPPE 1974) could be completed, because the number of observed eagles was increasing from 485 up to the number of 814 individuals. The structure of the fequency distributions for different periods are demonstrated corresponding, that there exists maxima in spring and autumn. These peaks can only be occured by a migration of eagles in the northern part of Germany. An additional explanation is the fact, that higher numbers of eagles were registrated at the flanks of the observed aerea, it means the counties of Schleswig-Holstein at the west side and Vorpommern at the eastern side. Losses during winter time are unknown. A disatvantage is the absence of discoveries of ringed birds, which would be an approvement for the theses of a migration in the northern parts of Germany. The relation between adult and immat. eagles was nearly 1:2,5.
