Abstract

Crvenokljuna čigra (Sterna hirundo Linnaeus, 1758) gnijezdi se u Hrvatskoj, često
kolonijalno, na šljunkovitim i kamenitim otočićima duž Jadrana te u porječju Save i Drave.
Najveće su kolonije ove vrste u Hrvatskoj kontinentalne, no te se populacije danas zbog
ljudskoga pritiska gotovo u potpunosti gnijezde na umjetnim staništima. U sklopu ove
disertacije, u trima znanstvenim publikacijama istraženi su odabir staništa kontinentalne
populacije crvenokljune čigre i njihovo kretanje među kolonijama pomoću GPS-UHF uređaja
za praćenje. Utvrđena su područja hranjenja crvenokljunih čigri koje se gnijezde u okolici
Zagreba, od kojih je najvažnije područje Save kod Hrušćice. Potvrđena je preferencija ptica
koje se gnijezde na koloniji Siromaja 2 za hranjenje na plićim dijelovima rijeke. Prvi put
dokumentirano je izviđanje odraslih ptica tijekom aktivnoga gniježđenja. Rezultati su ovoga
istraživanja korisne spoznaje i smjernice za pozicioniranje umjetnih gnjezdilišta, aktivnosti
restauracije riječnih ekosustava i procjenu utjecaja zahvata na crvenokljune čigre.

Abstract (english)

The Common Tern (Sterna hirundo Linnaeus, 1758) breeds, often colonially, in Croatia
on gravelly and rocky islands along the Adriatic Sea and along the Sava and Drava rivers. The
largest colonies in Croatia are found inland in freshwater habitats, but due to human pressure
these populations today breed almost exclusively on artificial sites. In this dissertation,
represented by three scientific publications, the habitat selection and movements of an inland
Common Tern population was investigated using GPS-UHF tracking devices. The area used by
Common Terns breeding near Zagreb was identified, the most important of which was the area
of Sava near Hrušćica. A preference of birds which bred at the Siromaja 2 colony was
established for foraging on shallow parts of the river. Prospecting of actively breeding adult
birds was documented for the first time. The results of this study provide useful insights and
guidance for the positioning of artificial breeding grounds, river ecosystem restoration
activities, as well as for assessing the impact of interventions in habitats of Common Terns.
