The International Commission on Zoological Nomenclature (ICZN) has used its plenary power to conserve existing usage of the name Columba liviaGmelin, 1789 for the common domestic pigeon by granting it precedence over the senior subjective synonyms C. domesticaLinnaeus, 1758, C. gutturosaLinnaeus, 1758, and C. cucullataLinnaeus, 1758. The ICZN has also used its plenary power to conserve existing usage of the trinomen Columba livia domesticaLinnaeus, 1758 by setting aside Article 24.1 of the Code and granting domesticaLinnaeus, 1758 precedence over gutturosaLinnaeus, 1758 and cucullataLinnaeus, 1758 whenever either of the latter two are considered a synonym of it.
