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.

New blog from BTO Senior Research Ecologist Ian Woodward for @ukrbbp.bsky.social delves into a new method for estimating breeding populations of Little Egrets. It discovered they were higher than previously thought – likely exceeding 2,000 pairs in the UK! #Ornithology

1/🧵 New BTO-led research sheds light on the number and range of Little Egrets with population estimates higher than previously thought – likely exceeding 2,000 pairs in the UK! 🙌 #Ornithology @britishbirds.bsky.social

Great to see RBBP data being used in work led by @btobirds.bsky.social that improves our knowledge on the status of Little Egrets in the UK… there are more than we thought!

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.

1/🧵 Two bird species bred in the UK in 2023 for the first time since the 1990s!

The latest report by @ukrbbp.bsky.social published in @britishbirds.bsky.social confirmed a pair of Hoopoes raised three young from a nest in Leicestershire and Rutland. #Ornithology

Our paper in December's @britishbirds.bsky.social describes success in using sound recording for detecting Lesser Spotted Woodpeckers. We found Lesser Spots still present in woodlands where they have not been seen/heard for years. This is very exciting www.woodpecker-network.org.uk/index.php/ne...

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
November 25, 2025 at 10:40 PM
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.

Thank you, Ian! We're really going to miss you on the panel - your broad knowledge of birds and habitats, questioning mind and great company have made you a wonderful person to work with.
After 25 years on the Rare Breeding Birds Panel, Dr Ian Francis stepped down last week. Ian has made an amazing contribution to the RBBP’s work, and he will be missed hugely. However, we hope this will give him more time to find rare breeding birds in Northeast Scotland and elsewhere!

We are saddened to hear of the death of Patrick Stirling-Aird, who for many decades was a leading light in the monitoring and conservation of raptors. It was a honour to work with Patrick on the Scottish Raptor Monitoring Scheme; we will miss him immensely. raptormonitoring.org/about-the-sr...

Raptor recovery… Marsh Harrier, Goshawk, White-tailed Eagle and Osprey have all increased substantially over recent decades. Ospreys have colonised new counties at the rate of one a year, including Co. Fermanagh in 2023, the first breeding on the island of Ireland in 200 yrs #ukbirding #ornithology
