BTO create and publish a variety of important articles, papers, journals and other publications, independently and with our partners, for organisations, government and the private sector. Some of our publications (books, guides and atlases) are also available to buy in our online shop.
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.

Population estimates of birds have a wide range of practical conservation uses, as well as being of enduring interest to many birdwatchers. Following previous reports by the Avian Population Estimates Panel (APEP), in 1997 and 2006, we present the third collation of population estimates of birds in Great Britain and the United Kingdom.

Fat provisioning in winter impairs egg production during the following spring: a landscape-scale study of blue tits

Although many of us provide food for garden birds, especially in winter, we are still only in the early stages of understanding exactly how this affects wild bird populations. One possibility is that winter food enhances birds’ ability to invest in future reproduction. However, it is likely that the type of nutrients a bird receives from supplementary food will be an important factor in determining whether this is the case. A new study by scientists at the University of Exeter, in collaboration with the BTO and the University of Turin, has shown exactly that.
