The cliffs are one of the most popular tourist destinations in Ireland and topped the list of attractions in 2006 by drawing almost one million visitors. Since 2011 they have formed a part of the Burren and Cliffs of Moher Geopark, one of a family of geotourism destinations throughout Europe which are members of the European Geoparks Network. The cliffs consist mainly of beds of Namurian shale and sandstone,[17] with the oldest rocks being found at the bottom of the cliffs. It is possible to see 300 million year-old river channels cutting through, forming unconformities at the base of the cliffs.[citation needed] There are an estimated 30,000 birds living on the cliffs, representing more than 20 species. These include Atlantic Puffins, which live in large colonies at isolated parts of the cliffs and on the small Goat Island. Also present are hawks, gulls, guillemots, shags, ravens and choughs.
