 abstract={France is an important staging and wintering area for both European races of cormorants: Phalacrocorax c. carbo (from Britain and Ireland) and Ph. c. sinensis (from Sweden, Poland, Germany and The Netherlands). In January 1992, all French roosts were censused and the wintering population was estimated at 66 000, these occuring at 27 roosts. This compares 14 000 in 1983. The increase of the wintering sinensis population in France triggered a recent change in the conservation status of this race; it can be now killed at all fish-ponds. This change could have some consequences for the dynamics of the European populations in some areas.},
