Abstract
The fifth review of Birds of Conservation Concern (BoCC5) in the UK, Channel Islands and Isle of Man assessed and assigned 245 species to updated Red, Amber and Green lists of conservation concern and showed a continuing decline in the status of our bird populations. In total, 70 species (29% of those assessed) are now on the Red list, up from 36 species in the first review in 1996. Since the last review, in 2015, Golden Oriole Oriolus oriolus has been lost as a breeding species. Eleven species have been moved to the Red list, while only six species moved from Red to Amber. Newly Red-listed species include Common Swift Apus apus, Common House Martin Delichon urbicum, Greenfinch Chloris chloris and the globally threatened Leach’s Storm-petrel Hydrobates leucorhous. There has been no improvement in the overall status of species associated with farmland and upland, or Afro-Palearctic migrants; indeed, more such species have been Red-listed. Concerns over the status of our wintering wildfowl and wader populations have also increased. As a direct result of targeted conservation action, White-tailed Eagle Haliaeetus albicilla moves from Red to Amber.
We also present a review of the separate, and distinct, second IUCN Regional Red List assessment of extinction risk for Great Britain, which show that 46% of 235 regularly occurring species, and 43% of 285 separate breeding and non-breeding populations, are assessed as being threatened with extinction from Great Britain.
An addendum was also published in Sept 2024, to update the status assessments of 28 breeding seabirds. Five additional files were added at that stage.

BACKGROUND
Birds of Conservation Concern (BoCC)is a well-established, well-respected process for identifying conservation priorities for UK birds, and uses quantitative assessments against standardised criteria to allocate species into one of three lists, ëRedí, ëAmberí or ëGreení, depending on their level of conservation concern. These reviews have a long history, with the first published in 1996.
the International Union for Conservation of Nature Red List process (IUCN) purely assesses extinction risk. Unlike BoCC, this approach allows different taxonomic groups to be assessed on a more level playing field, using the same well-established, internationally recognised criteria. This allows changes in status to be tracked and the potential creation of multi-taxa indicators (e.g. Red List Index). It is also worth noting that the IUCN Red List process can used at different spatial scales. Here, we use the standard Red list categories, e.g., Critically Endangered, Endangered, Vulnerable, to assess of extinction risk for Great Britain, as this is the scale national assessments are undertaken.
It is important to emphasise that BoCC and IUCN are two separate distinct assessment processes with differing aims.
ARCHIVE
This archive contains six supplementary files, relating to the above assessments, published in the journal British Birds in December 2021 (Stanbury et al. 2021):
1: BoCC5_GBIUCN2_supplementary_online_material.docx (created 2021-10-22) contains additional detailed information, not covered in the paper, on the processes used for both the BoCC5 and IUCN2, including species/race selection criteria, descriptions of assessment criteria, data sources and other methodological details.
2: SOM_Table_1_UK_BoCC5_species_results.xlsx (created 2021-10-22) contains species-level assessments for BOCC5. Each row represents a species/race, with the columns denoting whether they fulfil the various BoCC assessment criteria, as well as their final placement on either the BoCC5 Red, Amber or Green lists (Column J). Explanations of all criteria can be found in the Stanbury et al. (2021) and BoCC5_GBIUCN2_supplementary_online_material.docx.
3: SOM_Table_2_UK_BoCC5_race_results.xlsx (created 2021-10-22) contains race-level assessments for BOCC5. Each row represents a species/race, with the columns denoting whether they fulfil the various BoCC assessment criteria, as well as their final placement on either the BoCC5 Red, Amber or Green lists (Column J). Explanations of all criteria can be found in the Stanbury et al. (2021) and BoCC5_GBIUCN2_supplementary_online_material.docx.
4: SOM_Table_3_GB_IUCN2_species_results.xlsx (created 2021-10-22) contains species-level assessments for GB_IUCN2. Each row represents a species/race population, with the columns containing information relevant to the Regional IUCN Red List assessment, including generation length, qualifying criteria and final species/race threat status (Column R) with justifications for each stage of the Regional IUCN Red Listing process. Further explanations can be found in the Stanbury et al. (2021), BoCC5_GBIUCN2_supplementary_online_material.docx and IUCN (2019, 2012)
5: SOM_Table_4_GB_IUCN2_race_results.xlsx (created 2021-10-22) contains race-level assessments for GB_IUCN2. Each row represents a species/race population, with the columns containing information relevant to the Regional IUCN Red List assessment, including generation length, qualifying criteria and final species/race threat status (Column V) with justifications for each stage of the Regional IUCN Red Listing process. Further explanations can be found in the Stanbury et al. (2021), BoCC5_GBIUCN2_supplementary_online_material.docx and IUCN (2019, 2012)
6: Statement_of_voluntary_application_of_the_Code_of_Practice_for_Statistics.docx (created 2021-10-22) contains a statement about how the Birds of Conservation Concern Steering Group complied with the three main concepts, or pillars, of the UK governmentís Code of Practice for Statistics.
