Abstract

Velika sjenica (Parus major L.) je široko rasprostranjena ptica dupljašica iz porodice sjenica (Paridae). Za vrijeme sezone gniježđenja uglavnom se hrani gusjenicama, koje su najbrojnije u hrastovim šumama, što ih čini idealnim za gniježđenje i podizanje mladunaca. Cilj istraživanja bio je usporediti parametre gniježđenja velike sjenice u šumi hrasta lužnjaka i običnog graba u okolici Mokrica i bukovoj šumi na Ivanščici, kako bi se dobio uvid u utjecaj različitih čimbenika okoliša (temperatura, nadmorska visina, stanište) na njihovo gniježđenje. Uzorkovano je ukupno 50 aktivnih škrinjica, u svakoj je zabilježen broj i dimenzije jaja te broj mladunaca. Rezultati ne ukazuju na statistički značajne razlike između parametara gniježđenja velike sjenice u Mokricama i na Ivanščici te sukladno tome ne potvrđuju pretpostavku kojom se u hrastovim šumama radi bolje dostupnosti hrane očekuje veća prosječna veličina legla.

Abstract (english)

The Great Tit (Parus major L.) is widespread hole-nesting bird from the Paridae family. During the breeding season its main food are caterpillars, which are the most abundant in oak forests. That is the reason why these forests are ideal habitats for Great Tit's breeding and nestling rearing. The aim of this research was to compare Great Tit's breeding parameters in oak-hornbeam woods in Mokrice and beech woods in Ivanščica, and to test the influence of different environmental factors (temperature, altitude, habitat) on their breeding success. We analysed 50 active nest-boxes, counted number of eggs and nestlings in every nest-box and measured egg dimensions. The results do not show significant differences among breeding parameters in Mokrice and Ivanščica, and they do not confirm the hypothesis that clutch size is larger in oak woods because of better food supply.
