Abstract
Vrtna strnadica Emberiza hortulana izvan gnijezdeće sezone se osim beskralježnjacima hrani i sjemenkama dok mladunce hrani gotovo isključivo člankonošcima. Ovim istraživanjem je na području PP Učka u sezoni gniježđenja utvrđena učestalost hranjenja mladunaca i vrsta plijena (do razine reda) koju roditelji donose. Cilj istraživanja bio je utvrditi kako se veličina i vrsta plijena mijenjaju s dobom dana i starošću mladunaca te postoji li razlika među spolovima roditelja u učestalosti hranjenja mladih, vrsti i veličini plijena koji donose. Nakon provedenog kartiranja mužjaka u svrhu lociranja parova vrtne strnadice pronađena su aktivna gnijezda. Kamerama je zatim snimana prehrana mladunaca. Pregledom snimki i fotografija determiniran je plijen do razine reda te određen spol jedinki koje su mladuncima donosile hranu. Dokazano je da je za mladunce najvažniji plijen bio iz redova kornjaša i ravnokrilaca te ličinke leptira. Ličinke leptira bile su posebno važne u ranoj fazi razvoja dok su kasnije mladunci više hranjeni kornjašima i ravnokrilcima. Kornjaši su bili brojniji ujutro, a ravnokrilci i ličinke leptira popodne. Oba su roditelja kroz razvoj mladunaca preferirala manji plijen. Također, pokazan je veći broj dolazaka i učestalije hranjenje mužjaka.
Abstract (english)
Outside of the breeding season diet of ortolan bunting (Emberiza hortulana) comprises both invertebrates and seeds while chicks are fed almost exclusively on arthropods. I studied nestling feeding rate and type of prey (to the order level) delivered during the breeding season, in Nature Park Učka. The aim of this study was to determine if size and prey type change with time of the day, nestlings age, or between parents. After territory mapping to identify ortolan bunting territories, active nests were found. Nestling provisioning was then filmed with cameras. By reviewing tapes and photographs, I determined prey to the order level and sex of individuals delivering food. Results showed that beetles, orthoptera and butterfly larvae were most important for nestlings diet. Butterfly larvae were especially important during the first part of nestling period while later beetles and orthoptera were more frequent. Beetles were more abundant in the morning while orthoptera and butterfly larvae in the afternoon. Both parents preferred smaller prey. Also, males provided majority of prey.
