↑ In the past, this claim has been made on behalf of other species such as the red grouse (now considered to be a sub-species of willow ptarmigan) and Irish stoat (Mustela erminea hibernica), also now considered to be a sub-species of stoat. Loxia scotica 's position as a true species is a matter of debate but the current consensus is that it does have this status (see for example Miles and Jackman (1991) pp. 21–30 and Benvie (2004) p. 55.) The position of the freshwater fish the vendace Coregonus vandesius is disputed, with many authorities considering it to be a synonym of Coregonus albula.
↑ Adams, William Mark (2003) Future Nature. British Association of Nature Conservationists p. 30. Truy cập ngày 14 tháng 7 năm 2009. This source lists the UK's endemic species as being "14 lichens, 14 bryophytes, 1 fern, 21 higher plants, 16 invertebrates and 1 vertebrate (the Scottish crossbill)."
↑ Perhaps because endemic vertebrates are all but absent from the UK neither SNH nor JNCC appear to provide a definitive "list" but it is clear that the Scottish crossbill is the only endemic bird, (Gooders (1994) p. 273. and "Scottish Crossbill: Loxia Scotica (pdf) JNCC. Truy cập ngày 7 tháng 7 năm 2009.) and that there are no endemic freshwater fish (Maitland, P. and Lyle A.A. (1996) "Threatened freshwater fishes of Great Britain" in Kirchofer, A. and Hefti, D.

The position is implied, although not stated by SNH in their Information and Advisory Note Number 49 "Priority species in Scotland: animals" Retrieved ngày 7 tháng 7 năm 2009.

This publication confirms there is only one "endemic non-fish vertebrate species" in the British Isles, although it fails to identify the species concerned.
