BTO create and publish a variety of important articles, papers, journals and other publications, independently and with our partners, for organisations, government and the private sector. Some of our publications (books, guides and atlases) are also available to buy in our online shop.
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.

Development of a prototype early warning system for avian influenza in the EU based on risk-mapping
Author: Gargallo, G., Davies, J.G., Faverjon, C., Kampichler, C., Baillie, S.R., Cameron, A., Robinson, R.A. & Sierdsema H.

Outbreaks of high pathogenicity avian influenza (HPAI) have had a significant impact on the poultry industry and certain wild bird populations. Understanding the factors that lead to outbreaks is an important component of tackling the disease. The movements of migratory waterfowl have been linked to the spread of avian influenza, raising the question of whether existing data on bird movements could be used to develop an early warning system for the disease.

The Yellow-browed Warbler (Phylloscopus inornatus) as a model to understand the mechanisms of vagrancy and its potential significance for the evolution of new migratory routes
Author: Dufour, P., Åkesson, S., Hellström, M., Hewson, C., Lagerveld, S., Mitchell, L., Chernetsov, N., Schmaljohann, H. & Crochet, P-A.
Published: 2022
Why and how new migration routes emerge remain fundamental questions in ecology, particularly when viewed in the context of the current climate and biodiversity crises. We have already seen changes to migratory behaviour in some species, both in terms of the timing of movements and routes used, but identifying such changes at their earliest stage can be especially challenging, as this paper reveals.

Curves for Curlew: Identifying Curlew breeding status from GPS tracking data
Author: Bowgen, K.M., Dodd, S.G., Lindley, P., Burton, N.H.K. & Taylor, R.C.
Published: 2022
The Curlew is of significant conservation concern in the UK, and poor breeding success is thought to be one driver of this species' decline. However, breeding behaviour can be particularly difficult to observe first-hand. Can GPS tracking data help address these knowledge gaps?

High pathogenicity avian influenza: Targeted active surveillance of wild birds to enable early detection of emerging disease threats
Author: Wade, D., Ashton-Butt, A., Scott, G., Reid, S., Coward, V., Hansen, R.D.E., Banyard, A.C. & Ward, A.
Published: 2022
The disease Highly Pathogenic Avian Influenza (HPAI) has caused significant damage to both wild bird populations and the poultry industry. Detection of the disease has tended to rely on the sampling of dead birds following the reporting of mortality events, but could a different approach provide advance warning of potential outbreaks?
