BirdGuides 8190c212-33a2-40f5-a7ef-05b3d6ead33a Western Marsh Harriers have bred in the Republic of Ireland for the first time in more than a century, the Irish Raptor Study Group has announced. Two pairs of the species nested this summer in Cos Galway and Westmeath, with two young successfully fledging from each site. The last known breeding record of the harrier in Ireland was in 1917. Two pairs of Western Marsh Harrier bred succesfully in Ireland this summer (Sean Gray). Approximately 80% of the original extent of fens – key habitat for Western Marsh Harrier – in the Republic of Ireland has been lost to drainage for peat extraction and reclamation for agricultural land. The cumulative impact of wetland loss due to the Arterial Drainage Act 1945 and the preparatory drainage across bogs in Galway and Roscommon for energy production by Bord na Mona from 1946 limited any real prospect of the species returning in Ireland.
