Corncrake Bird
Corncrake Bird
Corncrakes are rarely seen or heard in Ireland today. Prior to the 1970's however, corncrakes had a large population here, numbering into the thousands. Current estimates place their population (based on the number of calling males) at 139 in 2002. Ireland is internationally important as a breeding ground for corncrakes. Their small population here accounts for 20% of their entire population over Western Europe. Corncrakes migrate to Ireland from Southern Africa to breed. They require cover (meadows, field margins, nettles and marshy areas) when they arrive and throughout the breeding season. With changing farming practices in Europe such areas are becoming increasingly rare. Grass is cut earlier and with heavy machinery to try and maximise the growing season, leaving no chance of escape or survival for hatchlings or eggs. But things are changing, with increased co-operation from farmers conservation measures are being put in place to try and prevent this bird from going extinct.

Dr. Arnold Horner, author of Physical Landscape.
Dr Horner has a long-time interest in the Geography of Ireland, broadly interpreted. More particularly, his study interests centre on Irish regions, especially the Dublin city-region, and the history of cartography in Ireland. He has twice been awarded a UCD President’s Research Fellowship, and he has also received awards from the former National Board for Science and Technology and the Irish Research Council for Human and Social Sciences. Dr Horner’s publications include contributions to a resource survey of Co. Kildare, census atlases on the agriculture and population of Ireland, and the section on Maynooth in the Irish Historic Towns Atlas. In recent years, Dr Horner has been researching the pioneering maps and surveys of the Bogs Commissioners of 1809-1814. His Mapping Offaly in the early nineteenth century: with an atlas of William Larkin’s map of King’s County 1809, was published by Wordwell in November 2006.
