INTRODUCTION

        SOUTHERN MOUNTAINS AND CRAGS

           he highest, harshest, snowiest peaks of southern European
        Tmountains are little different from their counterparts in the
        north, but many others are snow-free and characterized by big, bare
        crags, dizzying cliffs, and deep gorges with rushing rivers. Forests of
        beech, oak, and pine climb high on the mountain slopes, creating
        conditions that attract woodland species more characteristic of
        northern Europe.The southern influence, however, remains strong,
        with the presence of birds of prey hunting overhead, and, in the
        valleys, many other species that are not found farther north.
        HABITAT MIXTURE
        With their peaks, high pastures, and valleys, mountainous
        areas bring together a variety of habitats within a small
        area. From one spot it is possible to see riverside birds,
        woodland birds, and those characteristic of grassy pastures
        and hedgerows, as well as species that prefer cliffs and  COASTAL CLIFFS

         STUNNING PEAKS
         High mountain peaks with deep gorges and
         shady valleys have a great range of birds of prey,
         many of which nest lower down but move up
         each day to hunt over high ground. Cliff faces
         have their own unique birds – some move out
         to feed on high-altitude grassy meadows.
