NatureScot has published the results of the International Census of Greenland Barnacle Goose in Great Britain and Ireland for 2020 and 2023.

Main findings include:

• A ground and aerial survey of Greenland barnacle geese in Scotland in February 2023 found 48.332 birds, a decline of 16.9% compared to counts made in March 2020.
• Including counts from Ireland, the total population count in 2023 was 62.159 geese, which represents a 15.3% decline from the previous census in March 2020 when 73.391 geese were counted.
• Due to poor weather conditions, the aerial survey in Scotland was undertaken on 26-27 February 2023. Ground counts were mostly undertaken between 18 and 26 February 2023. In Ireland, the count was largely conducted on 23-24 February. Coverage was thought to be good in both countries.
