Annual report of the Seabird Monitoring Programme
Seabird Population Trends and Causes of Change: 1986–2023
This report presents the latest seabird population trends in breeding abundance and productivity using data from the Seabird Monitoring Programme (SMP).
The report documents changes in the abundance and productivity of breeding seabird species in Britain and Ireland from 1986 to 2023, and provides a detailed account of the 2021, 2022 and 2023 breeding seasons.

Winter wren populations show adaptation to local climate
Author: Morrison, C.A., Robinson, R.A., & Pearce-Higgins, J.W.
Published: 2016
BTO research reveals that one of our most widespread songbirds – the Wren – varies in its resilience to winter weather, depending on where in Britain it lives. Scottish Wrens are larger than those living in southern Britain, and are more resilient to hard winter frosts.

Playback survey trial for the Little Owl Athene noctua in the UK
Author: Clewley, G.D., Norfolk, D.L., Leech, D.I. & Balmer, D.E.
Published: 2016
Little Owls are in decline in the UK, but are hard to monitor, making it difficult to establish this species' conservation and management needs. Newly-published research by the BTO demonstrates how playback could be an effective tool for helping to detect and monitor this species.
