Abstract

Five annual avian censuses (1968-69, 1972-73, 1982-83, 2001-02, 2008-09) were conducted in the period between 1968 and 2009, since the Cristoforo Colombo Genoa Airport was functional. Despite the different purposes of the individual studies, researchers applied a common approach of visual and vocal identification. Qualified personnel weekly surveyed accessible areas of the airport. This paper summarizes the findings of the five researches. A checklist of the 137 species observed includes phenology, quantitative changes, and their trend over the entire period. Relative abundance of dominant and sub-dominant species was computed within each survey. The generalist/opportunist species have gradually asserted themselves throughout the years with regard to ecological needs.
