Abstract Distance and direction of natal dispersal were studied in a Polish White Stork (Ciconia ciconia) population on the basis of 25 years of banding and resighting data. Multiple regression analysis showed a significant sex-linked bias (females settled farther from the natal sites than males) and effect of banding year, in that dispersal distances were decreasing toward the end of the study period. Population indices in the hatching year and the presumed recruitment year did not help to explain the variance. The birds showed a trend toward settling southeast of the natal site, but this was significant only in individuals that settled within 50 km of the natal site. We suggest that when returning from winter sites in the southeast, young White Storks settle before they reach their presumed migratory target in the vicinity of the natal site. This is only possible if, in spite of a relatively high population density, many breeding areas and potential nesting sites remain vacant. This might also explain our failure to find density dependence in the interannual variation of dispersal distances.

In this paper is presented the situation of the White Stork breeding from several villages in the Argeş County and Olt County, in 2021. The data were collected during the White Stork Census in Romania, coordinated at the national level by the Romanian Ornithological Society (SOR) and Milvus Group. We checked the presence of nests in the 7 localities in Argeș County and Olt County using the car and the GPS track. The data is used to calculate numbers and study population trends of the species in Romania. An analysis was performed on several indicators (uH, HPo, HPm, Hpa, H, JZG) that characterize the reproduction, as well as other facts about the distribution. The results were compared with those from the previous White Stork census in Argeş County, in 2004 and 2014. Although the population of the White Storks from Argeş County shows a slight increase in this localities, the anthropogenic pressure is strong, in addition the dry climate, from the south of Arges County, strongly affects, at local level, the population of the White Storks.
