  1. Any species or subspecies which has not yet been recorded in Categories A, B or C in Ireland.
  2. All the species and subspecies included in Appendix 1.

The IRBC reserves the right to ask observers for substantiating details of records of species and subspecies involving exceptional numbers, unusual dates, etc. including those listed in Appendix 2. For a full account of the background and reasons behind these changes click here.


The list of species and subspecies included in Appendix 1 & 2 are subject to periodic review. Details of any changes made to the lists will be added to the Announcement pages. The most recent decisions may be read by clicking here.
