Analysis of data from long-term monitoring schemes gives a total wintering waterbird population estimate in Great Britain of 12.8 million individuals for 2017/2018 to 2022/2023. While this total is unchanged from the previous estimate, there have been notable shifts, with numbers of estuarine waders, Whooper Swans, Little Egrets and non-migratory geese increasing, and declines in several duck and goose populations, including Bewick’s Swan, Pink-footed Goose and Teal.
