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 investigate the role of productivity in House Sparrow Passer domesticus population trends

Author: Morrison, C. A., Robinson, R.A., Leech, D.I., Dadam, D. & Toms. M.P.

Published: 2014

Although House Sparrows are conspicuous birds and can still be found cheeping away in many areas, their numbers have fallen sharply in recent years, leading to their inclusion on the Birds of Conservation Concern Red List. Declines are greater in urban than in rural areas, and in eastern and south-eastern Britain than in other parts of the country (where the population is stable or increasing).  A new study by the BTO has used data collected by volunteers participating in Garden Birdwatch (GBW), the Nest Record Scheme (NRS) and the Breeding Bird Survey (BBS) to investigate possible reasons underpinning these trends.
