The reemergence of the highly pathogenic avian influenza virus (HPAIV) subtype H5N1 in the United Kingdom in 2021-2022 has caused unprecedented epizootic events in wild birds and poultry. During the summer of 2022, there was a shift in virus transmission dynamics resulting in increased HPAIV infection in seabirds, and consequently, a profound impact on seabird populations. To understand the pathological impact of HPAIV in seabirds, we evaluated the virus antigen distribution and associated pathological changes in the tissues of great skua ( Stercorarius skua , n = 8), long-tailed skua ( Stercorarius longicaudus , n = 1), European herring gull ( Larus argentatus , n = 5), and black-headed gull ( Chroicocephalus ridibundus , n = 4), which succumbed to natural infection of HPAIV during the summer of 2022...
