Species Action Plans Scottish Crossbill (Loxia scotica)
Although this species has a small range, it is thought to be stable and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). The population size is large, and hence does not approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern. [source: Birdlife.org]
[Scottish Crossbill (Loxia scotica) Europe 1999]
The Scottish Crossbill Loxia scotica is the UK’s only endemic bird species. The Scottish Crossbill was given specific status in 1980 (BOURC 1980). However, the specific status of this bird is unclear due to taxonomic confusion and difficulty in distinguishing between this species and the Common L. curvirostra and Parrot Crossbills L. pytyopsittacus (HMSO 1995). The Scottish Crossbill is believed to be resident in the central and eastern Highlands of Scotland, and mostly confined to Caledonian pine forest and old pine plantations. Little is known of recent trends in Scottish Crossbill numbers. Over recent centuries, however, it is likely that its range and numbers have contracted with the long-term reduction in the area of Caledonian pine forest. It is ‘SPEC 1’ (status insufficiently known) and is priority listed in the UK Biodiversity Action Plan, with a published Species Action Plan (Biodiversity: The UK Steering Group Report – volume 2: Action Plans). It is ‘red-listed’ in Birds of Conservation Concern in the UK (Gibbons et al 1996) and also fulfils ‘amber-list’ criteria as it breeds in internationally-important numbers in the UK (100%), and is a localised breeding species confined to a vulnerable habitat. It is protected under Schedule 1 of the Wildlife and Countryside Act 1981; Annex 1 of the EC Birds Directive; Appendix II of the Berne Convention.
