Osprey, Pandean helianthus.Osprey, Pandean helianthus. In Poland its quite rare, the number of predatory birds is estimated to be approximately 30-40 breeding pairs, although that number still falls and not yet able to restore the number of representatives of several years when it was over 90-100 pairs breeding. Occurs across, and Wielkopolska. This is strictly protected. When I began to find his remains, the formation of the species is estimated to be Pleistocene, and it was found that he lived in Europe but also in America and the Bahamas Islands. It was found that five subspecies lives in Poland subspecies. Because Poland is the migration route the Swedish and Finnish, we can see it all over Poland in the period from March to May and from July to October. The main factors of degradation of the species are acts of man. Too much use of illegal fishing methods such as use of electricity makes it a lack of food for this predator.
