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.

Modelling changes in species' abundance in response to projected climate change
Author: Renwick, A.R., Massimino, D. Newson, S.E., Chamberlain, D.E., Pearce-Higgins, J.W. & Johnston, A.
Published: 2012
There has been plenty of work on the effect that climate change might have on the range of particular bird species; for example, Dartford Warbler is predicted to extend its range north with an increase in temperature. However, for the first time, scientists at the British Trust for Ornithology have looked at what effect climate change might have on the distribution and abundance on particular species.

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.
