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.

Rise of the Generalists: evidence for climate driven homogenization in avian communities
Author: Davey, C.M., Chamberlain, D.E., Newson, S.E., Noble, D.G. & Johnston A.
Published: 2012
Research by the BTO, just published in the journal Global Ecology and Biogeography, shows that the diversity of Britain’s birds has increased with a warming climate, but this was accompanied by a loss of habitat specialists.

Modelling large-scale relationships between increasing abundance of deer and changes changes in bird populations in lowland England
Author: Newson, S.E., Johnston, A., Renwick, A.R., Baillie, S.B. & Fuller, R.J.
Published: 2012
Newly published work by BTO scientists suggests that the increasing abundance of three widespread deer species, Reeves’ Muntjac, Roe Deer and Fallow Deer, have contributed to population declines of several breeding woodland birds in lowland England.

Declines in Afro-Palearctic migrant birds are linked to bioclimatic wintering zone, possibly via constraints in arrival time advancement
Author: Ockendon, N.O., Hewson, C.M., Johnston, A. & Atkinson, P.W.
Published: 2012
Many UK-breeding birds that migrate to Africa for the winter have undergone dramatic declines in recent decades. New BTO research shows that both winter habitat and the geographical regions visited had a significant effect on population trends between 1994 and 2008, as measured by data from the Breeding Bird Survey.

Composite bird indicators robust to variation in species selection and habitat specificity
Author: Renwick, A.R., Johnston, A., Joys, A., Newson, S.E., Noble, D.G. & Pearce-Higgins, J.W.
Published: 2012
Ecological indicators that measure the state of the environment are of growing political importance due to national and international conservation obligations. Birds are commonly used as biodiversity indicators because of their high trophic level, sensitivity to environmental change, public popularity and relative ease of survey. Indicators of general environmental health based on breeding bird population trends (from and BBS) have therefore become important drivers of conservation and land-use policy in the UK and further afield.
