Data from: The fifth review of Birds of Conservation Concern in the United Kingdom, Channel Islands and Isle of Man and second IUCN Red List assessment of extinction risk of birds for Great Britain

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.

英国、海峡群岛及马恩岛的第五版《保育关注鸟类》（Birds of Conservation Concern, BoCC5）审查报告，对245个鸟类物种开展评估并将其归入更新后的红色、琥珀色与绿色保育关注名录，同时揭示本国鸟类种群的保护现状仍在持续下滑。
目前共有70个物种（占评估物种总数的29%）被列入红色名录，较1996年首版审查报告中的36个物种有所上升。
自2015年上一版审查报告发布以来，金黄鹂（Oriolus oriolus）已不再作为繁殖物种分布于该区域。
共有11个物种被新增列入红色名录，而仅有6个物种从红色名录调整至琥珀色名录。
本次新增列入红色名录的物种包括普通雨燕（Apus apus）、家毛脚燕（Delichon urbicum）、欧金翅雀（Chloris chloris）以及全球受胁的利奇氏风暴海燕（Hydrobates leucorhous，即白腰叉尾海燕）。
与农田、高地生境相关的鸟类物种，以及非洲-古北界迁徙鸟类的整体保护现状未有任何改善；事实上，更多此类物种被纳入了红色名录。
公众对本国越冬水禽与鸻鹬类种群保护现状的担忧亦有所加剧。
得益于针对性保育行动，白尾海雕（Haliaeetus albicilla）已从红色名录调整至琥珀色名录。
本报告同时对大不列颠地区的第二份独立专属IUCN区域红色名录灭绝风险评估进行了综述：在235种定期出现的鸟类物种中，有46%的物种，以及285个独立繁殖与非繁殖种群中的43%，被评估为在大不列颠范围内面临灭绝威胁。
本报告还附带2024年9月发布的增刊，用于更新28种繁殖海鸟的保护现状评估，同期新增了5份附属文件。
