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.

Diversity of response and effect traits provides complementary information about avian community dynamics linked to ecological function
Author: Hordley, L.A., Gillings, S., Petchey, O.L., Tobias, J.A. & Oliver, T.H.
Published: 2021
Species vary widely in their ecological and functional traits. Ecosystems containing a wide variety of different traits usually function better and provide more ecosystem services to humans than more homogeneous ecosystems. However, the choice of traits selected to represent diversity within a community can affect our ability to understand ecosystem processes.

Designing effective survey and sampling protocols for passive acoustic monitoring as part of the national bat monitoring
Author: Newson, S.E., Boughey, K.L., Robinson, R.A & Gillings, S.
Published: 2021
The UK has one of the best developed bat monitoring programmes in the world, but despite this, six of 17 resident bat species in the UK are not currently monitored sufficiently to produce population trends. Large-scale deployment of passive acoustic methods using full spectrum bat detector technology offers a lot of potential for transforming routine monitoring of bat numbers, but it is essential that effective survey and sampling protocols are used if this potential is to be realised.

Recovering the Eurasian Curlew in the UK and Ireland: progress since 2015 and looking ahead
Author: Douglas, D.J.T., Brown, D., Cohen, S., Colwell, M., Donaghy, A., Drewitt, A., Finney, K., Franks, S., Heptinstall, D., Hilton, G., Kelly, S., Lindley, P., McCarthy, B., McCulloch, N., O’Donoghue, B., Sanders, S., Thompson, P. & Whitehead, S.
Published: 2021
Work in 2015 identified Curlew as the UK's most pressing avian conservation priority. New research reviews progress since that time, both in the UK and the Republic of Ireland, and concludes that there has been little change in this species' precarious status.
