Abstract:The feeding habits of the Cormorant wintering in the Maremma Natural Park have been assessed through the analysis of pellets collected in the winter of 1991-92 and 1992-93. In both years the quantitative-qualitative analysis of the pellets showed the presence of a rnuch greater percentage of Mullets (Mugilidae) than of other fishes: 60% in nurnber and 90% by weight; the mean size of the fish was 21.5 cm. The rnean fish weight ingested daily, estirnated from the pellet contents, was 278 g in 1991-92 and 377 g in 1992-93.
