We depart from our primary topic of birds in this episode to explore the world of Spiders. Who better to talk to on the topic but Collie Ennis, spider expert, Research Associate at Trinity College and Scientific Officer with the Herpetological Society of Ireland (www.thehsi.org/).  From a spiders life-cycle, to murderous mates and sub-aquatic species we learn heaps from a wonderful conversation with Collie. Our Bird of the Week is the is the Treecreeper, a species that enjoys more than a few spiders in its diet.  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 Ciarán O'Connor.
