Abstract

A study on the Sicilian avifauna changes and its existing connections with the land use variations has been carried out from the80s till today. We compared the Sicilian ornithological data acquired from the atlas maps with the regional land use maps data. We examinedthe land use variations and the distribution changes of some bird species on a regional level. To this aim, we analyzed the spatial distributiondata of the birds in the period from 1984-1992 and 1993-2006. Moreover we examined the land use data of the period going from1987-1988 and 1993-2000. After a preliminary analysis, we selected target species linked to different environments. Forest: Great spottedWoodpecker Dendrocopos major, Mistle Thrush Turdus viscivorus, Long-eared Owl Asio otus, Eurasian Nuthatch Sitta europaea,Marsh Tit Poecile palustris siculus ; scrub and bush: Red-backed Shrike Lanius collurio, arable and grazing land: Greater short-toed LarkCalandrella brachydactyla, Calandra Lark Melanocorypha calandra; complex systems, olive grove and almond trees: European RollerCoracias garrulus, Woodchat Shrike Lanius senator. The distribution changes of these species in the examined periods were significantand they were not linked to the demography of the species nor to the major or minor level of exploration of the island. According to theresults, it is obvious that, for these species, there is a clear connection between the land use changes and the distribution variations. Otherspecies manifested changes that seemed to be linked to demographic trends, which involved the distribution of these species (for examplethe diffusion of the Wood Pigeon Columba palumbus). None of the existing changes could be unequivocally related to climate change.
