Credit where it's due, I saw this story on the Raptor Politics blog. Ireland has banned poisons for pest control, other than the regular rat and mouse baits. Story in the Irish Independent here.
Not surprisingly this is being hailed as a victory, not just for Ireland's birds of prey but also for Scotland - much of the poison used illegally in Scotland comes across the water. Raptor Politics is hopeful that supplies will eventually dry up, although I somehow doubt it will have any noticeable effect in the foreseeable future. Apart from anything else, anyone keen to kill birds of prey illegally will find a way.
