2026 Rookery Survey
Rooks are busy nest building at this time of year and the Herts Bird Club is once again asking submission of Rookery nest counts in Hertfordshire in 2026.
In 2025, 228 Rookeries with 4338 nests were found, a big increase on the 2024 totals as a result of better observer coverage. Rooks have been surveyed for a long period in Hertfordshire going back to a complete survey in 1960/61 where 521 Rookeries with 15739 nests were found (Sage & Nau, 1963). Numbers declined until the 1990's, but appear to be stable since, with a loss of Rookeries in the south of the county and trend towards more but smaller Rookeries (Knight, Herts Bird Report 2021).
