Co-operation with a national wildlife conservation organisation in tourism destinations, e.g. Bird Watch Ireland - the largest independent conservation organisation in Ireland, is also a medium- to long-term option for sustainable tour operator engagement - http://www.birdwatchireland.ie. Customers may also participate in all-important bird counts at certain times of the year – a hands-on, educational and memorable highlight, indeed, of any round-trip to the Emerald Isle. Such occasions are also valuable press and social media promotion opportunities. Bird species now under greatest threat in Ireland include the Buzzard, the Curlew, the Corncrake, Barn Owl, the Kestrel and the Yellowhammer.
