Since humans occupied and began to alter our landscape there have been winners and loosers amongst our bird species. Humans impact on the avifauna of Ireland has been mostly negative with persecution, over hunting and habitat destruction/loss being big drivers in the extinction process.  Ricky and Niall look at some species that are long extinct, some that have slipped away in the recent past and others that have returned. Some fabulous species feature in this episode including, the bittern, the common crane, the marsh harrier and corn bunting among them. The chat ends on a positive note as it turns to the potential of the midlands bogs to host thriving populations of cranes, bittern, marsh harrier and other wetland specialists.  In Your Nature is produced in partnership with the Heritage Offices of Laois and Offaly County Councils, supported by the Heritage Council and the Department of Housing, Local Government and Heritage, and is edited by Ann-Marie Kelly
