The Eurasian Crane (Grus grus) in Ireland - another extinct bird or a key species for an ancient belief system?

The dwindling Gaelic language is an ancient Indo-European language, spoken on the once isolated island of Ireland. Early Irish Manuscripts suggest Cranes were once the third commonest pet, after dog and cat. The arrival of Christianity and the 16th century extinction of Irish Cranes may have undermined its status. The Gaelic word for Crane is 'Corr/Cor'. Over a thousand Irish Place names begin with the prefix Cor, though 19th century English translations rarely mention the forgotten Crane. Other Gaelic words also hint at the importance of Cranes, as attested elsewhere in the world. For example, the phrase ‘Corr Uimhir’, arguably suggesting ‘Crane Number’, is translated as ‘Odd Number’ in modern literature. Gaelic language speculation may hint at an ancient relationship between Cranes and the unknown original Proto-Indo-European counting system. The Onomatopoeic name Cor, and cognates such as Kor and Gor and their ablauts, may reward expert international multi-disciplinary focus.
