AB  - Understanding the movement pattern and ranging behavior of the Griffon vulture population in Serbia is of great importance for prioritizing conservation action. In 2011, an immature vulture was the first bird to be equipped with a satellite transmitter in Serbia. Our study aims to define the vulture's foraging areas, home ranges, core and basic areas, and to investigate movement patterns across different years and seasons by analyzing satellite telemetry data. We tracked the movements of the vulture for over three years and obtained satellite tracking data for 34 bird-months (1976 GPS fixes) between October 2011 and July 2014. We determined that the overall foraging area of the vulture across the entire study period was 11654.34 km(2). The overall area used by the vulture was larger during spring and summer than during winter periods. Combined ranges across all years identified one basic area and its associated core area around the Uvac colony and nearby feeding site; we identified three core areas in its proximity. This study showed that areas of traditional stock-raising practices are important vulture foraging areas and that supplementary feeding sites have a vital role. Our maps can be used for future planning of vulture conservation measures.

AB  - The Eurasian griffon population in Serbia declined throughout the 20th century from widespread to a rare species, counting a total of 14 detected pairs in two colonies in western Serbia in the 1990s. Although the conservation measures have been implemented since the 1970s, they have had little effect on the further population decline until the supplementary feeding program started in 1989. In this paper, we present the results related to the population trends and reproduction parameters, following the establishment of a supplementary feeding program of the Eurasian griffon in Serbia based on a 34-year survey (1985-2018). By 2018, a total of 2458 tons of supplementary food was provided at three feeding stations. The population increased from 14 detected pairs in two colonies in 1992 to 262 detected pairs in four colonies in 2018. A total of 1807 juveniles were fledged, with breeding success - fledged chicks/laying pairs (i.e., breeding pairs) (0.81 +/- 0.07; mean +/- SD) and productivity - fledged chicks/detected pairs (0.57 +/- 0.10). The amount of supplementary food was in a significant positive correlation with the number of detected and breeding pairs and the number of fledged juveniles. Furthermore, breeding parameters remained high despite the substantial increase in population size, implying that the population is far from saturation level. Our study emphasizes the importance of applied protection measures, especially supplementary feeding. The implementation of appropriate networks of feeding stations and the promotion of free-range livestock farming, as well as returning to the traditional way of disposing of dead cattle, would be a recommendation for future main conservation activities for the Eurasian griffon population in Serbia.

AB  - Great cormorants (Phalacrocorax carbo) are piscivorous birds, and as apex predators they accumulate high levels of contaminants from the aquatic ecosystems. In the present study, we analyzed distribution of Al, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Sr, and Zn in ten tissues (muscle, liver, kidney, spleen, gizzard, heart, skin, lard, breast feathers, and remiges) of the Great cormorants in the Marin Sprud locality, the Danube River, Serbia. Concentrations of elements in tissues were assessed by using inductively coupled plasma optical spectrometry. Linear discriminant analysis indicates that breast feathers and remiges have a high bioaccumulation potential for heavy metals (Cr, Pb, Sr, and Zn). Those tissues had the highest concentrations of lead (Pb) (2.179 +/- 0.742; 0628 +/- 0.282). Maximum concentrations of mercury (Hg) were detected in liver (30.673 +/- 14.081), followed by kidney, for the same element (17.409 +/- 5.676), respectively. The overall maximum metal accumulation was observed in breast feathers and remiges, followed by liver and kidney, whereas the minimum values were observed in muscle, skin, and lard. The greatest concentrations of Cr, Ni, Pb, Sr, Zn, and Al were detected in feather tissues. Our study confirms that great cormorant is a good indicator species for monitoring of pollution of river and wetland ecosystems.
