Sažetak
Recognising changes in distribution and/or abundance of bird species is a starting point in establishing their successful protection. In Croatia, there are tenths of bird species that are known to have changed breeding range and/or abundance in the last decades. However, there is no organised national monitoring of birds scheme running yet. There have been several publications on the distribution of birds in Croatia, all of which encompass smaller geographic scale, scattered across the Croatian territory (Washington 1890, Csörgey 1903, Reiser 1939, Maštrović 1942). Only one comprehensive research was undertaken from 1946 to 1975 on the Croatian coast (Rucner 1998). The data from that research were collected across the whole Croatian coast in habitats influenced by a Mediterranean climate (Figure 1). The area is dominated by the distinctive formation of Dinaric Karst, with a limestone geological base. The primary climatogenic communities have a character of forests, and secondary communities, which have developed from forests by degradation, have a character of scrubland (e.g. maquis), dry grassland, and karstic fields (Horvatić 1971). In order to get a better idea on what has been going on with the breeding birds in this area we compared Rucner’s observations with data we collected in recent years (2004- 2009). We have also tried to evaluate the reasons for the observed changes.
