BirdTrends 2023

BTO’s BirdTrends 2023 report provides summary information about the population status of the common breeding birds of the wider UK countryside. The report is based on data gathered by the many thousands of volunteers who contribute to BTO-led surveys.

Summary Statistics

• Results from more than 20 time series are available in the BirdTrends 2023 Summary Statistics.

Previous BirdTrends reports, up to and including BirdTrends 2022, included species pages displaying the latest information on trends in population size, breeding performance and survival rates for 121 species, as measured by our long-term monitoring schemes.

The species information contained in previous BirdTrends reports has now been incorporated into BirdFacts, which now provides a one-stop, easy-access location to review all the existing knowledge that is available about all the species found in the UK.

• All links to individual species in the latest BirdTrends report now point to the relevant species page in BirdFacts.

Key Findings

However, the BirdTrends report itself continues to provide an overall summary of current trends in more than 120 UK bird species and is designed to be used in conjunction with the BirdFacts species pages.
