Circaetus gallicus information navigator

The Lublin Ornithology Society started their projects on GPS-GSM telemetry of local adult Short-toed Eagles in 2012. Some results of them are available on sites of the society, as well as conservation programs. Just use the Polish name of the species «Gadożer» as a search word to find info regarding Short-toeds in the submitted files:

Also, you can read some fresh news about observations of local Short-toed Eagles on the LTO page on Facebook, and enjoy this short video taken at the nest of a pair where the male is tagged with the GPS-GSM transmitter.

The articles about Short-toed Eagles in present southwestern /map/ and southeastern /map/ Poland are divided by about 80 years. Four of them, written by Viktor Zebe /map/ and published in the first half of the 20^th century, have been placed on the Ptaki Śląska – Birds of Silesia website (De):

The next paper by Adam Flis is available on a website of the Institute of Nature Conservation PAS:

• Adam FLIS, 2013 – Występowanie gadożera Circaetus gallicus w Lasach Janowskich i Lipskich [The occurrence of Short-toed Eagle in Janowskie and Lipskie Forests (SE Poland)] // Chrońmy Przyrodę Ojczystą, 69 (3): pp. 221–225. – (Pl).

Just some articles containing basic facts on distribution, biology and ecology of Short-toed Eagles in Poland, Ukraine and Bulgaria:

After 153 days of silence GSM transmitter of the adult Short-toed Eagle female tagged in Poland in 2012 started working again in Africa on March 1^st. So, Polish ornithologists could mark her spring migration route receiving coordinates of her location each hour. The route was different from the autumn one: the bird visited Greece and Ukraine where she was travelling during almost 3 weeks, maybe because of the bad weather conditions, but finally she achieved the old breeding territory in Poland /map/. Her partner was observed there on April 17^th with caught snake in his beak. The female joined him 2 days later.

You can find more information about the project on the Lublin Ornithology Society website and you can see detailed descriptions of the Short-toed Eagle’s adventures on the LTO page in Facebook (Pl). Also please view the migration map:

Adult Short-toed Eagle female was equipped with a GPS-GSM logger in the southern part of Lublin Province /map/ (south-eastern Poland) this year. She started the autumn migration quite early. Detailed information is available on the Lublin Ornithology Society site. The migration map can be viewed here. Please note: each red point on the map is provided with a detailed comment.

This is the presentation of two old texts of the first part of the XX century. One of them was written by Viktor Zebe:

• Viktor Zebe, Oktober 1936 – Zur biologie des Schlangenadlers [Biology of the Short-toed Eagle] – Berichte des Vereins Schlesicher Ornithologen /map/. Just read the translation of it (Fr) from German made by one of the greatest adepts in Short-toed Eagles in France – Yves Boudoint.

The second is Nikolay Gavrilenko‘s work, that is mentioned in the first one:

• Гавриленко Н.И., 1929 – Птицы Полтавщины. Змееяд [The birds of the Government of Poltava. Short-toed Eagle] // Полтава: Издание Полтавского союза охотников: 28-30 (Ru) /map/.
