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.

How should static detectors be deployed to produce robust national population trends for British bat species?
Author: Stuart Newson
Published: 2017
There is growing use of full-spectrum bat detectors to survey bats and other taxa. When used in conjunction with call identification software and validation, these detectors have the potential to transform large-scale bat monitoring in the UK. However, there are several questions to be answered regarding how these detectors should be best deployed.

Projected reductions in climatic suitability for vulnerable British Birds
Author: Massimino, D., Johnston, A., Gillings, S., Jiguet, F. & Pearce-Higgins, J.W.
Published: 2017
Researchers have long investigated the effects that climate change might have on species’ future ranges. However, for the first time, scientists at BTO have used abundance data to project the future distribution and abundance of more than one hundred breeding birds in Great Britain in order to assess how the whole bird community might change as a consequence of climate change.
