The difference in habitat use by the observed waterbird species at Rački ribniki (Rače Ponds, NE Slovenia) was studied between June and August 2011. It was assessed that different waterbird species, ...even closely related species like
ducks, use wetlands differently, with Tufted Ducks
observed more on Open water and Ferruginous Ducks
more often amongst Floating vegetation. The latter was used more often probably due to the abundance of food in the habitat. Highest species richness was recorded on Floating vegetation as well. This was reflected in species richness of individual ponds, where ponds with more floating vegetation had higher species richness. Although Coots
were expected to utilize Floating vegetation more often due to their feeding preferences, they were observed more often on Open water probably feeding on fish fodder available there. The difference in habitat use by the families and nonbreeding individuals of the same species was noted, too, mostly by observing families in habitats that provide more cover from predators (Reeds), or more invertebrate food (Floating vegetation) for the young that often feed on different food than adults. Furthermore, it was suggested that overall management of wetlands should consider providing more suitable wetlands with larger aquatic vegetation cover.
Prikazuje park ob hotelu Palace, viden je ribnik, obdan s koriti z rastlinjem. Desno in levo od ribnika so palme v ravni vrsti in pod njimi pisane rože. V ozadju je morje, na katerem je jadrnica, ...in polotok Seča s tedanjim skladiščem soli.
