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.

Exclusion of deer affects responses of birds to woodland regeneration in winter and summer
Author: Holt, C.A., Fuller, R.J. & Dolman, P.M.
Published: 2014
Native and non-native deer populations are increasing in temperate woodlands across Europe. Previous work by the BTO found that these changes are associated with declines in some breeding bird populations, and suggested this is due to modification of the woodland understorey through browsing (consumption of vegetation by herbivorous deer). Now a new study by the BTO and the University of East Anglia has demonstrated effects of deer activity on birds outside the breeding season.

The value of a random sampling design for annual monitoring of national populations of larger British terrestrial mammals
Author: Wright, L.J., Newson, S.E. & Noble, D.G.
Published: 2014
Mammals are an important part of the UK’s biodiversity but can be difficult to monitor, requiring special surveys to determine their distribution or how their populations are changing over time. However, some widespread and easily detected species, such as deer, rabbits and squirrels, can be monitored as part of bird surveys.

Indicators of seabird reproductive performance demonstrate the impact of commercial fisheries on seabird populations in the North Sea
Author: Cook, A.S.C.P., Dadam, D., Mitchell, I., Ross-Smith, V.H. & Robinson, R.A.
Published: 2014
New research led by the BTO shows that the UK’s internationally important seabird populations are being affected by fishing activities in the North Sea. Levels of seabird breeding failure were higher in years when a greater proportion of the North Sea’s sandeels, important prey for seabirds, was commercially fished.

Modelling flight heights of marine birds to more accurately assess collision risk with offshore wind turbines
Author: Johnston, A., Cook, A.S.C.P., Wright, L.J., Humphreys, E.M. & Burton, N.H.K.
Published: 2014
New research by the BTO reveals that most seabirds fly near the sea surface, avoiding collision with wind turbines by flying under the blades. Those birds that fly higher above the sea are at greater risk of collision. Building offshore turbines higher above the sea surface, or installing fewer large turbines instead of several smaller turbines, could reduce the number of collisions.
