This year's autumn migration has begun. As in recent years also this year we will try to present the jpurney of the eagles fitted with our dataloggers. This year we have: last year's juvenile hybrid which spent the season in Romania,21-year-old GSE female which logger records data for the second year in succession and juvenile female hybrid from Kampinos - Bogusia.
Feel free to track their migration in the Greater Spotted Eagle - Migration - 2014 Migration Map menu.
Poor year for Spotted Eagles
Disaster. This single word describes best this year's situation on Biebrza. All because of draught caused by the snowless winter, rainless spring and never ending sunny summer make the marshes vanising right before our eyes. Add proceeding melioration. As the result you can drive through the marshes not only with special machinery, but also with normal cars.
Greater Spotted Eagle in Kampinos
Good news from the Kampinos Primeval Forest where a successful breedings of mixed pair between female Greater and male Lesser Spotted Eagle was recorded this season. It is one of the few cases of GSE nesting outside the Biebrza Valley in Poland. The rest comes from the Lublin area.
In cooperation with the Kampinos National Park employees the juvenile bird - a female - was ringed and the "Aquila" company founded a datalogger. She was also given a name - Bogusia. Let us hope the eagle will safely reach its maturity and will successfully breed in the future.
Yet another fulvescens on Biebrza
Today a Spotted Eagle of the pale form, so-called fulvescens, was observed on the Biebrza Marshes. The eagle, with some features pointing towards the Greater Spotted Eagle, was soaring accompanied by a Common Buzzard Buteo buteo and chasing him Lesser Spotted Eagle Aquila pomarina, all taking advantage of the sunny weather.
It is the second observation of this form of the Spotted Eagle in recent years. The last record comes from summer of 2011.
A book on the Greater Spotted Eagle
The last step of the ending Greater Spotted Eagle project is the publication of a book which has just seen the daylight. It's entitled "The Greater Spotted Eagle - Vanishing Bird of the Marshes" and was written by world's experts on the field: Dr. Grzegorz Maciorowski, Jan Lontkowski and Dr. Tadeusz Mizera. The book contains comprehensive knowledge on the species' distribution and biology in Polandand compares this knowledge with the results of the research performed on Greater Spotted Eagles in other countries. The advantage of the publication is undoubtedly it's multilingual form - the book contains full translations from the Polish language into both English and Russian.
The "Aquila" company contributed to this publiction by translating parts of the text free of charge and delivering many photographs, including the cover one.
