Latest Breeding Bird Survey results - JNCC

The latest annual report from the Breeding Bird Survey, extending to the year 2022, and incorporating the Waterways Breeding Bird Survey, are now available, providing population trends of the UK’s breeding birds.

The BTO/JNCC/RSPB Breeding Bird Survey (BBS) is a UK-wide scheme for monitoring changes in the breeding populations of the UK’s common and widespread breeding birds. In the most recent annual (2022) report, population trends for 118 bird species in the UK have been produced.

The results show that, across the UK, 37 species have significantly increased in the long term (since 1994), whilst 41 species have significantly declined. However, some species that are in decline are too rare to be monitored robustly, so may not be included in these figures. In addition, population increases include the expansion of recent colonists and non-native species.

As in previous years, the largest long-term increases are for Little Egret and Red Kite, whilst long-term declines continue for Turtle Dove, Willow Tit and Wood Warbler. There are also some positive signs for the farmland species Skylark and Corn Bunting, which have seen severe long-term declines in the past. The Skylark, which has seen a decline of 14% at a UK scale since 1995, and even greater declines since the 1960s, has increased by 9% over the past 10 years and by 8% in the past five years.

At a country- or regional-level the trends are a little more mixed. For example, the report shows that the Skylark has increased by 9% in England and 16% in Scotland over the past decade, with even more promising increases of nearly 20% over five years in south-east England and 10 years in the East Midlands. However, the recent increases in England and Scotland are not mirrored in Wales, where there has been a 23% decline since 2016. In Northern Ireland, numbers have been stable over the past decade, though this is set against a decline of 40% since 1994. These country-and regional-level trends allow us to understand both pressures such as climate change on species, and the effectiveness of action for nature recovery, at a more local scale.

The latest report can be found on the BTO (British Trust for Ornithology) website.
