Abstract

Bela štorklja Ciconia ciconia velja za modelno vrsto raziskovanja selitve ptic. Selitve ptic so ponavljajoči se premiki med gnezdiščem in prezimovališčem ob približno istem času spomladi in jeseni. Selitveni vzorci juvenilnih in odraslih osebkov bele štorklje se med seboj razlikujejo, saj juvenilni osebki še nimajo ustaljenih selitvenih poti. Razumevanje selitvenih vzorcev med juvenilnimi belimi štorkljami je še precej neraziskano, vendar je znano, da je njihova smrtnost med selitvijo večja kot pri odraslih osebkih, kar lahko vpliva na velikost celotne populacije. V Sloveniji smo prvič opravili raziskavo selitvenih vzorcev juvenilnih osebkov bele štorklje. Z GPS/GSM oddajniki smo opremili deset juvenilnih belih štorkelj na gnezdih na Dolenjskem podolju, Krški ravni in Ljubljanskem barju. S pridobljenimi podatki smo opisali prvo selitev juvenilnih belih štorkelj iz Slovenije, določili in izračunali osnovne parametre selitve, opisali prezimovališča juvenilnih belih štorkelj ter ugotavljali smrtnost osebkov juvenilnih belih štorkelj med prvo selitvijo in prezimovanjem na območju Afrike. Večina proučevanih osebkov je za prvo selitev izbralo t. i. vzhodno selitveno pot, ki velja za glavno selitveno pot vzhodne populacije belih štorkelj. Bele štorklje so prezimovale predvsem na območju Podsaharaske Afrike, ki velja za pomembno prezimovališče tako vzhodne kot zahodne populacije belih štorkelj. Za vse primere smrti belih štorkelj, za katere smo ugotovili vzrok, je bil kriv človek, ki je s svojimi dejanji bodisi neposredno bodisi posredno vpliv na osebke bele štorklje.

Secondary title:	Migration patterns of juvenile White Storks Ciconia ciconia from Slovenia
Secondary abstract:	The White Stork Ciconia ciconia is considered as a model species for the research of bird migration. Bird migrations are repeated movements between the nesting and wintering sites at approximately the same time in spring and autumn. There are differences between migration patterns of juvenile and adult specimens of the White Stork, as juvenile specimens do not yet have established migration routes. The understanding of migratory patterns of juvenile White Storks is still considerably unexplored. However, it is known that their mortality during migration is higher than the mortality of adults, which may affect the size of the entire population. For the first time in Slovenia, we conducted a survey of migration patterns of juvenile White Storks. We equipped ten juvenile White Storks with GPS/GSM transmitters on their nests in the Dolenjsko podolje, Krška ravan and Ljubljansko barje. With the obtained data, we described the first migration of juvenile White Storks from Slovenia, determined and calculated the basic migration parameters, described the wintering sites of juvenile White Storks and determined the mortality of juvenile White Storks during their first migration and wintering in Africa. Most of the studied individuals chose the so-called Eastern migration route for their first migration, which is considered the main migration route of the eastern population of White Storks. The White Storks wintered mainly in the Sub-Saharan Africa, which is considered as an important wintering site for both eastern and western populations of White Storks. All cases of the death of White Storks, for which we found the cause, were caused by humans, through direct or indirect actions, which influenced the individuals of White Storks.
