Country diary: For the gannets of Bass Rock, it's a slow road to recovery | Lev Parikian

Bass Rock is home to around 100,000 gannets, but bird flu hit the population in 2022. A recent study by the RSPB and Aarhus University showed it will take the birds at least 15 years to recover. Many survivors now have black irises instead of their usual vivid blue eyes.
