The Alps, their birds and what we know about them. For a long time little was known about the distribution and ecology of birds in the Alpine region. Increasing research efforts in the challenging mountain environment have improved our knowledge of this highly important region.
The Alps are characterised by a wide range of habitats and altitude levels, featuring a high species diversity on a small scale although species richness declines with increasing altitude, in particular above the tree limit. Some species in Switzerland find suitable habitats only in the Alps (Rock Partridge, Bearded Vulture, Blue Rock Thrush), for others they mark the edge of their range (Grey-headed Woodpecker, Blue Rock Thrush). Some species, e.g. the Alpine Swift, extended their range from their centre of distribution in the Alps. For species suffering from the intensive land use in the lowlands the Alps have become their last refuge (Eurasian Skylark, Whinchat).
Climate change is likely to put some Alpine species at risk. The Rock Ptarmigan in particular, is expected to lose large parts of its current range. Switzerland with its large mountainous areas has an international responsibility for several Alpine species. Therefore, the situation of these species has to be monitored closely, in particular in agricultural areas and conservation measures have to be applied where needed.
