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.

Using citizen science to assess drivers of Common House Martin breeding performance
Author: Kettel, E.F., Woodward, I.D., Balmer, D.E. & Noble, D.G.
Published: 2020
House Martin numbers in the UK have declined by 39% over a 25 year period, but it is unclear why. This small hirundine is a summer visitor that spends the winter months in an unknown part of sub-Saharan Africa, returning to build their cup-shaped nests under the eaves of buildings during April and May. In the 2016 and 2017 breeding seasons, BTO ran the House Martin Nest Study which involved members of the public monitoring the breeding behaviour of House Martins nesting close to where they lived.
