Sažetak
Impact of climate warming on the biota is being seen worldwide and in the last few decades numerous published works describe this problem. Special attention has been focused on phenology. This paper is based on the results of the 37-year phenology monitoring of the European starling (Sturnus vulgaris) breeding population in the Mokrice area, northwestern Croatia. The European starling is semi-colonial, hole-nesting, short-distance migrant and common bird species in the northwestern Croatia. In this study, long-term changes in the clutch initiation date and in the average local air temperature (March-April) from 1980 to 2016, has been investigated. During the study period, average spring temperature in the research area increased significantly. Furthermore, clutch initiation date of European starling was significantly advanced during the same period. Correlation between clutch initiation date and average spring temperature was found to be significant. These results indicate that investigated bird species advanced its breeding date by approximately eight days between 1980 and 2016 in the northwestern Croatia. On the basis of this finding, it is concluded that the European starlings are breeding earlier in the last few decades in the northwestern Croatia and that this advanced nesting is likely caused by warmer spring temperatures
