Decline and recovery of the White-tailed Eagle Haliaeetus albicilla in Central Europe and in some breeding sites in Mecklenburg-Vorpommern. White-tailed Eagles are birds whose occurrence and distribution have been known for a long time and have been described repeatedly. For the first time their history between the 19th and 21st century is presented with a few examples of five chosen breeding sites and of two breeding ranges, the island of Rügen and the river Peene with the nature reserve Anklamer Stadtbruch in Mecklenburg-Vorpommern. During this time the White-tailed Eagles experienced two large direct and indirect human interventions on their populations. In the second half of the 19th century, they were almost exterminated in Germany and Europe due to direct persecution. 50 years later, the second threat due to the pesticide DDT led to low breeding success and a stagnation of the population for about 30 years. When the use of DDT was prohibited and the population began recover up around 1980, the increase was clearly stronger than in the first half of the 20th century and is still carrying on undiminished. The reasons lie in improved food availability due to the eutrophication of the shallow marine areas, lakes and rivers since the middle of the last century.
