Long-term effects of bird flu on Gannet colonies in Scotland and Wales

 
Photo and headline:  RSPB, 7/3/2026

According to a new study led by the RSPB and Aarhus University, Gannet populations at two of the world’s largest colonies, Bass Rock in Scotland and Grassholm in Wales, are not expected to recover from the impact of bird flu until 2041 at the earliest. 
The findings show bird flu was responsible for a fourfold increase in the deaths of adult Gannets. The UK is responsible for a high proportion of the global population. 
In the 11 years prior to 2022, the average annual mortality rates were 6% at Bass Rock and 11% at Grassholm. During the outbreak, this rose to 33% and 47% respectively.\ 
In 2023, a year after the outbreak, this led to a 26% decrease in the size of the colony at Bass Rock and a 38% decline at Grassholm.
