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.

Why is timing of bird migration advancing when individuals are not?
Author: Gill, J.A., Alves, J.A., Sutherland, W.J., Appleton, G.F., Potts, P.M. & Gunnarsson, T.G.
Published: 2013
The BTO is involved in new research led the University of East Anglia, showing that young birds are the trend-setters when it comes to migration. It had generally been believed that the flexibility of individuals to respond to warmer springs lies behind the phenomenon of advancing migration. In this paper, focusing on the changing arrival dates of Black-tailed Godwits in Iceland, the authors show that individual, colour-ringed birds are not changing their schedules over time. Instead, it is the earlier spring migration of birds hatched in more recent years that lies behind the observed pattern of advancing arrival for the species.

State of Nature report 2013
Author:
Published: 2013
The report summarises information on trends in more than 3100 species within the major taxonomic groups assessed. The report presents a new Watchlist Indicator, a cross-taxa priority species indicator that tracks changes in the abundance of 155 high priority species for conservation for which trend data are available. This demonstrates that, overall, conservation efforts to reverse the declines in these species have not yet succeeded, and highlights the need to refine the Watchlist Indicator and produce comparable measures from a broader range of species.This report is an excellent use of the population trends produced with the high quality bird data collected in the BTO’s major partnership schemes.
