SUKB collates data from annual, periodic and one-off surveys and monitoring studies of birds, such as the Breeding Bird Survey (BBS), Rare Breeding Birds Panel (RBBP), the Wetland Bird Survey (WeBS), Seabird Monitoring Programme (SMP) and Goose and Swan Monitoring Programme (GSMP). In addition, the 2020 report also includes results from the Nest Record Scheme, Constant Effort Sites (CES) Scheme and Re-trapping Adults for Survival (RAS) Scheme, the latter two schemes collecting demographic information through the efforts of bird ringers.
The report takes information from these and other schemes, research and surveys and delivers information at a country-specific scale, as well as providing an overview for the UK as a whole.
Volunteers play an essential role in bird monitoring in the UK, by donating their time, energy and expertise. The data they collect are vital for conservation, tracking changes in populations and supporting policy development. This year, many monitoring schemes have been adversely affected by the global COVID-19 pandemic and we want to say a special thank you to all of our volunteers for their continued support through this difficult time. Their skill, effort and dedication deserve huge recognition.Sarah Harris, BBS National Organiser
This year’s report highlights the continuing poor fortunes of the UK’s woodland birds. The UK Wild Bird Populations Indicator for woodland species show a long-term decline of 27% since the early 1970s, with declines of 7% evident over just the last five years. More worryingly, when looking at individual trends within the report, some specialist woodland birds have declined dramatically, including Willow Tit with a 94% decline since 1970 as illustrated by the joint Common Birds Census / Breeding Bird Survey UK-wide trend.
After worrying declines in breeding Tawny owl populations were flagged-up by the Breeding Bird Survey, BTO launched targeted survey work on this species during 2018 and 2019. SUKB reports on some of the results from this research, which revealed a decline in site occupancy from 65% in 2005 to 53% in 2018/19. The BTO work has also sought to understand some of the reasons for this change in fortunes.
Results at different scales
Data from many of the surveys covered in SUKB also feed into European-wide schemes and the SUKB report goes from celebrating the publication of the latest European Breeding Bird Atlas, through to finer-scale country-specific results and research. Not bad for an 80 page report!
Country-specific headlines include increases in House Sparrow populations in Wales, where work is also taking place to address the pronounced decline in Curlew numbers. In Scotland, the fragile status of Corncrake is highlighted, alongside increases in farmland species such as Tree Sparrow and Yellowhammer. The Northern Ireland pages look into changing fortunes of seabirds and explore how proposed marine Special Protection Areas may be used to tackling the observed decline. The Northern Ireland pages also examine declines in wintering geese, such as Light-bellied Brent Goose. Finally, over to England and promising results for Stone Curlew conservation work, as well as reporting back on the English Winter Bird Survey for which 1,485 sites were surveyed by volunteers to help us understand the value of agri-environment options.
As in previous reports, we hear about species from 14 UK Overseas Territories and three Crown Dependencies – including Black-browed Albatross, St Helena Plover and South Georgia Pipit, about the Gough Island Restoration Programme, and discover that 69 species in the Overseas Territories and Crown Dependencies are now Globally Threatened.
Closer to home, 25 years of BTO Garden BirdWatch is also celebrated, with Goldfinch now the 8th most commonly recorded garden bird, up from 20th back in 1995.
There is a common theme in this report: volunteers. The sheer enormity of their contributions to bird monitoring as a whole is evident throughout this report. Most of the surveys and schemes covered here are only possible thanks to the dedication and skills of the thousands of volunteers who give up their time to help monitor birds and in turn, inform conservation action. Thank you.
Who produces this report?
SUKB 2020 is produced by a coalition of three NGOs: the Royal Society for the Protection of Birds (RSPB), the British Trust for Ornithology (BTO) and the Wildfowl & Wetlands Trust (WWT), together with the UK’s statutory nature conservation bodies: Department of Agriculture, Environment and Rural Affairs, Northern Ireland (DAERA), the Joint Nature Conservation Committee (JNCC), Natural England (NE), Natural Resources Wales (NRW) and NatureScot.
Our volunteers: the beating heart of BTO data
Head and Principal Ecologist, David Noble, shares why volunteer-collected data are so important for an organisation like BTO.
The Seabird Monitoring Programme (SMP) works to support the protection and conservation of our internationally important seabird populations.
