The UK supports internationally important populations of breeding seabirds. BTO is a partner in Britain and Ireland's Seabird Monitoring Programme and supports the current national census – Seabirds Count. Information from BTO's Retrapping Adults for Survival scheme and Nest Record Scheme also contributes to our understanding of seabird demography. Through analyses of data and field-based tracking projects, our research considers the many drivers of seabird population change, including climate change and renewable energy schemes.
