How does an osprey protect itself

Osprey

Ospreys belong to the falcon family. The medium-sized birds of prey reach a body length between 55 and 60 centimeters with a wingspan of 1.50 to 1.70 meters and are distributed almost worldwide. Ospreys feed primarily on fish. You therefore need a habitat with fish-rich, slowly flowing waters or lakes. Appropriate breeding opportunities in the vicinity are particularly important. And here lies the problem: nesting sites are rare.

The osprey lacks nesting sites

Ospreys are one of the least threatened species in Finland, and an estimated 1,100 breeding pairs are still there. Nevertheless, ospreys also have to struggle with problems: The heavy nest of the birds of prey requires a stable tree as a base. But the number of old forests with a suitable tree population is steadily declining in Finland due to forestry use. As a result, the ospreys lack nesting sites. The WWF is committed to protecting forests and promoting biodiversity in productive forest areas.

Partner for a lifetime

Osprey pairs stay together for a lifetime. They spend the winter mainly in West Africa and raise their young in Finland, among other places. Between April and May the female lays one to four eggs and incubates them. She is fed by the male.

For a long time, ospreys were heavily persecuted because they were considered food competitors. As a result, they were temporarily exterminated in Western Europe. But now the slender eagles are regaining their habitats. In Central Europe, ospreys are mainly found in eastern Germany and Poland. Large populations could be held in Finland and the rest of Scandinavia.
