Category D species
Species in Category D would otherwise appear in Category A, except that there is reasonable doubt that they have occurred in Britain in a natural state. Species placed only in Category D form no part of the British List, and are not included in the species totals.
Category D is a holding category and is not intended to be a long-term assignment of any species. The species are reviewed periodically with a view to assign them to either Category A or Category E.
Descriptions are required of records by the British Birds Rarities Committee (BBRC) to be considered for inclusion in Category A of the British List.
These species form no part of the British List.
