Impact of local air temperatures on the brood size in Starling (Sturnus vulgaris L.)

Many papers over recent years demonstrated long-term temporal trends in biological parameters that can only be explained by global warming. I examined the long-term trends in the brood size of Starling (Sturnus vulgaris) in Mokrice area (north-western Croatia). I collected data from 1977 to 2007. To nvestigate the effect of spring temperatures on the brood size, local air temperatureswas used. The significant corelationn (P<0.01) between mean brood size and the year (y = - 31.403 + 0.18x) indicates that brood size (mean number of nestlings per nest) increased 0.54 nestling over the period of the study. Correlation between brood size (mean number of nestlings per nest) and mean spring temperatures was also significant (P<0.05). The correlatin between mean spring air temperature and research year was significant (P<0.01). This data show that the mean May temperature has been increasing in the study aea. We can conclude that Starlings in north-western Croatia are increasing their brood size and that the most likely cause is a long-term increase in spring temperatures.
