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.

Avian malaria-mediated population decline of a widespread iconic bird species
Author: Dadam, D., Robinson, R.A., Clements, A., Peach, W.J., Bennett, M., Rowcliffe, J.M. & Cunningham, A.A.
Published: 2019
England’s House Sparrow population fell by 70% between 1977 and 2016, and this once ubiquitous species is now absent from many urban areas. New research involving the BTO has found evidence that malarial parasites may be linked to this species’ decline.
