On the 29.07.2020. the Birds of Prey Protection Foundation from Belgrade, in cooperation with the Managing body of the “Vršac Mountains” and the Institute for Biological Research “Siniša Stanković”, the Institute of National Importance for the Republic of Serbia, University of Belgrade, with the permission of the Ministry of Environmental Protection, installed a suitable satellite transmitter on the Short-toed Eagle Circaetus gallicus, which was in his natural nest. The transmitter was financed by the company “Telekom Srbija” a.d. Belgrade.

The Short-Toed Eagle is a migratory species that spends the winter in sub-Saharan Africa. This nest in the Vršac Mountains has been monitored by ranger Milivoj Vučanović for more than a decade. Until now, there were data on the activities of a pair of Eagles, the success of nesting, but now we have the opportunity to monitor their young on his journey to Africa and back, with all the data provided by this methodology.
The young female has been given the name “Ognjenka”. The bird was big, in good condition. She was professionally processed, ringed with a metal ring of the Center for Marking Animals of the Natural Museum in Belgrade, as well as a plastic ring (mark “AL”, red color on the left leg). She was tagged with 25 grams “Ornitela” GPS/GSM satellite transmitter, with solar power as well, and the bird was safely returned to the nest.

17.08.2020. The bird began to leave the nest and move around.
27.09.2020. Ognjenka started her autumn migration at around 10 am. On the first day, she flew about 200 km.
09.10.2020. After 12 days of autumn migration, Ognjenka arrived in Africa. She happily passed the very dangerous zone of Turkey, Syria, Lebanon, Israel, crossed the Suez Canal, enter the Egypt and now, following the Nile, descends to the south and her destination where she will spend the winter.
15.10.2020 Ognjenka “called” from Sudan. She flew 5.272 km and arrived in sub-Saharan Africa.
25.10.2020. Ognjenka “stationed” in the south of Sudan and now is moving less, hunting around. The autumn migration is over and here are some details of how it went:
The migration lasted from 27.09.2020. (Vršac Mountains, Serbia) until 25.10.2020. (Sudan), or 28 days.
She flew a total of 6765 km, on average 270.6 km per day.
She flew the longest daily distance on the 11.10.2020, 364 km, in Egypt, following the Nile River.
The highest recorded altitude was 3056 m above sea level, 10.10.2020, at 11:47:44 (UTC), Egypt (GPS: 24.9449 33.401.28).
The highest recorded speed was 96 km/h, 13.10.2020, at 14:49:47 (UTC), Sudan (GPS: 15.73369 31.81189).
NOTE: Now Ognjenka is in the part of Africa where the GSM signal coverage is poor, so it is possible that we will sometimes wait for a long time for a new data.
