Abstract

As wintering Whooper Swans Cygnus cygnus have shifted
their winter feeding habitats from water to terrestrial
ones, the International Waterfowl Counts, covering only
coastal and lake sites since its start in 1967, cannot monitor

covering also the terrestrial habitats have been organized
in mainland NW Europe every ive years since 1995. In
January 2015, about 12 000 Whooper Swans were recorded
in Sweden, an increase from 7400 in 1995. On

came irst in the southernmost province of Scania where
