Seabirds Count Datasets

The results from Seabirds Count, the fourth census of Britain and Ireland’s internationally important populations of breeding seabirds, were published on 16 November 2023. Over 10,000 sites and 25 species were surveyed between 2015 and 2021 to provide a comprehensive update on the state of these populations and gain greater insight into the relationships between them and the pressures they face. Full species’ accounts of Seabirds Count census results can be found in the Seabirds Count publication, available to purchase from Lynx publishing. Several datasets are available to download, including: * The comparative dataset for Seabird 2000 and Seabirds Count (previous versions (November 2023, December 2023) replaced July 2024 to address some minor errors). * The dataset used to produce the Manx Shearwater and European Storm-petrel estimates. * A full summary of all population estimates, and total percentage change recorded for each species across all 173 SPAs.
