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.

The acoustic identification of small terrestrial mammals in Britain
Author: Newson, S.E., Middleton, N. & Pearce, H.
Published: 2020
Britain is home to several species of small mammals, which include rats, mice, voles, dormice and shrews. All of these are difficult to observe in the wild, and it is usually necessary to capture them to confirm their presence. By describing the vocal repertoire of small mammals in Britain, research published in British Wildlife by a team led by the BTO provides new possibilities for sound identification to be used as a non-invasive survey method.

Strengthening the evidence base for temperature-mediated phenological asynchrony and its impacts
Author: Samplonius, J.M., Atkinson, A., Hassall, C., Keogan, K., Thackeray, S.J., Assmann, J.J., Burgess, M.D., Johansson, J., Macphie, K.H., Pearce-Higgins, J.W., Simmonds, E.G., Varpe, Ø., Weir, J.C., Childs, D.Z., Cole, E.F., Daunt, F., Hart, T., Lewis, O.T., Pettorelli, N., Sheldon, B.C. & Phillimore, A.B.
Published: 2020
A newly published assessment of the evidence that climate change is causing biodiversity populations to decline as a result of divergent changes in the timing of consumer demands and the availability of species that they feed on, highlights significant evidence gaps.
