The Cairngorn Mountains boast some bird species that are only found in these extreme conditions. One of the unique creatures that are adjusted to the snowy, cold, and wind-prone mountain range environment is ptarmigan and dotterel. Ptarmigans that are exquisite white birds turn grey-brown in summer, while dotterels are social birds that flock in large numbers only during summertime. Ptarmigan or dotterel sightings during other parts of the year in these rocky mountain ranges are rare to find. Show more
