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.

The avoidance rates of collision between birds and offshore turbines

Author: Cook, A.S.C.P., Humphreys, E.M., Masden, E.A., Band, W. & Burton, N.H.K.

Published: 2014

Report of work carried out by the British Trust for Ornithology in collaboration with the Environmental Research Institute on behalf of the Marine Scotland Science. Accurately estimating birds’ risk of collision with offshore wind turbines is a key part of the decision-making process for proposed renewable developments. However, the evidence base for quantifying the number of birds likely to avoid colliding with turbines is limited. Recent BTO-led work helping to fill this gap, improving the understanding of the impacts of offshore renewables on marine wildlife.

Latitudinal gradients in the productivity of European migrant warblers have not shifted northwards during a period of climate change

Author: Eglington, S. M., Julliard, R., Gargallo, G., van der Jeugd, H. P., Pearce-Higgins, J. W., Baillie, S. R. and Robinson, R. A.

Published: 2014

A long-term monitoring study involving bird ringers from five countries has investigated how changes in the reproductive output of seven species of migrant warbler vary with latitude and spring temperature. The implications for predicted changes in species distribution are also discussed.

A global assessment of the conservation status of the nominate subspecies of Eurasian oystercatcher (Haematopus ostralegus ostralegus)

Author: Van de Pol, M., Atkinson, P.W., Blew, J., Duriez, O.P.M.B., Ens, J., Hälterlein, B., Hötker, H., Laursen, K., Oosterbeek, K.H., Petersen A., Thorup, O., Tjørve, K., Triplet, P., Yésou, P.

The nominate subspecies of Eurasian Oystercatchers Haematopus ostralegus ostralegus is the most abundant of all oystercatchers and the best studied. The main breeding and wintering areas are centered on the North Sea, but the distribution covers the European Atlantic coast to as far south as Ghana in western Africa. Population size increased strongly from the 1960s to 1990s to over one million birds. Although part of this expansion may have been caused by an ongoing successful adaptation to breeding inland, the main driving forces behind this increase are not well understood. Subsequently, the population size decreased substantially by about 200,000 individuals, mainly due to strong decreases in the Dutch-German-Danish Wadden Sea area. The decrease in the Netherlands is attributed largely to overexploitation by mechanical shell-fisheries; additional factors such as agricultural intensification and reduced eutrophication are likely to also have contributed. The causes for the decreases in Germany and Denmark are less well understood and urgently require further study. In other areas numbers are fairly stable or increasing, but good data for the Nordic countries are lacking. The global (and national) conservation status of H. o. ostralegus is classified as of ‘Least Concern’. We discuss other threats, such as habitat loss, climate change, hunting and human disturbance, and make prioritized recommendations for research and management.
