To distinguish the smaller Procellariiforms of the family Hydrobatidae from the larger petrels of the family Procellariidae on the Irish List, the IRBC is adopting the vernacular name Storm-petrel for the following species:
- Wilson's Petrel becomes Wilson's Storm-petrel
- Storm Petrel becomes European Storm-petrel
- Leach's Petrel becomes Leach's Storm-petrel
- Swinhoe's Petrel becomes Swinhoe's Storm-petrel
- Madeiran Petrel becomes Madeiran / Cape Verde / Monteiro's Storm-petrel. See also: 'Changes to the Irish List April 2013'
