New Indicator for Wintering Waterbirds in Scotland
New Indicator for Wintering Waterbirds in Scotland09 Sep 2021
This indicator tracks the population trends of 41 species, which are primarily counted by volunteers taking part in the BTO/RSPB/JNCC Wetland Bird Survey (WeBS), supplemented with additional targeted counts for geese and swans, and periodic surveys of rocky shore waders (the Non-Estuarine Waterbird Survey, NEWS).
This indicator showed that overall waterbird numbers have decreased by 7%. Much of this decline is explained by waders, with numbers for the 14 species monitored 58% lower than in winter 1975/76. There was more positive news for ducks and swans (16 species), which increased by 21%, and geese (seven species/populations), which rose in number by 274%.
