Size and distribution of briding colonies of Grey Heron Ardea cinerea in lowland Croatia

Grey Heron Ardes cinerea is the most abudant heron species in Croatia, with an estimated population of 1500 - 3000 pairs. We conducted a survey of existing colonies during the 2004 breeding season and counted 3674 pairs in 19 colonies. Based on this data the Grey Heron breeding population thresholds should be increased primarly along the remaning floodplains of the Danube, Drava, Sava and Kupa rivers as well as on commercial cyprinid fishponds
