Wintering Population of the Common Cormorant Phalacrocorax Carbo Sinensis in Tuscany, Italy
Common Cormorants of the Continental race Phalacrocorax carbo sinensis have recently increased their breeding populations, since some European countries have stopped control measures against them (Hansen, 1984; Hald-Mortensen, 1985; Rooth, 1985). This fact, not completely analyzed in the 1970’s (Cramp & Simmons, 1977) is now also affecting numbers observed on wintering grounds (Hansen, 1984; Suter, 1985).
