The ptarmigan

The higher slopes facing north, covered with rocky debris, dwarf willows and a few grasses, are the preferred habitats of a rare glacial relict, such as the alpine ptarmigan. Its survival in a climatic phase like the current one is put at risk, its biology does not allow it to adapt so quickly to changing high-altitude environments. It will only survive on the cooler slopes of high mountains, as its ability to move is relatively small.
