Résumé :	This is the third assessment of the population status of birds in the UK. The listing criteria are based on global conservation status, historical population declines, recent population declines (both in numbers and in geographical range), European conservation status, breeding rarity, localised distribution, and the international importance of populations. For consistency, the criteria follow closely those used by previous reviews, with minor modifications where new information or methods are available. We have assessed the population status of 247 species in the UK: 40 (c. 16%) were placed on the 'Red list', 121 (c. 49%) on the 'Amber list', and 86 (c. 35%) on the 'Green list'. The number of Red-listed species has increased by four, and the number of Amber-listed species by eleven since the previous review in 1996. Nine new species have been added to the Red list because of declines in their breeding populations, while thirty-one species have remained Red listed. Five species have moved from the Red to the Amber list because their populations have more than doubled in the last 25 years.
