We encourage and support the recording of rare breeding birds in the UK, collate data in order to report annually on their numbers, trends and distribution, and maintain a secure archive to support conservation and research on these species.

4/Roseate Tern numbers fell from 154 pairs in 2022 to 118 in 2023 following deaths of 90 adults from bird flu in the 2022 breeding season. Although breeding numbers were lower than prior to bird flu, there are signs of hope with 2024 representing the second most successful breeding season on record.

3/ However, there’s also some concerning news from the report. In northern Scotland, numbers of Slavonian Grebes fell to just 16 pairs, the lowest total since the @ukrbbp.bsky.social began reporting in 1973.

2/A pair of Temminck’s Stint laid four eggs in 2023 but sadly the nest was washed out by rising water levels.
The report also revealed 15 species reached record totals in 2023! This included White-tailed Eagle, with 160 pairs in the UK, and Marsh Harrier, which reached 500 pairs for the first time.

Most other species near our 2,000 pr threshold are concentrated into relatively few breeding sites (e.g. Med Gull), or have a significant annual monitoring effort (e.g. Peregrine). These make data collation, often of a high % of the pop, comparatively easy. This certainly isn’t true for Willow Tit

There was a good case, yes, but with a population nearly three times our threshold, we felt that this was too much mission creep, especially given our limited resources. Hopefully repeated national surveys will track the population, and more effectively than our data collation could.
