Golden eagle

If you hear a single, sharp whistle in the Alpine valley, the king of the Alps can't be far away. Marmots are by far the most common food for this elegant bird of prey. Using the updraught of the mountain slopes, the golden eagle spirals upwards, disappears behind a mountaintop and suddenly emerges over the marmot colony. But with just one whistle, the marmots dive into their holes and the eagle flies away empty-handed. Plenty of feed must be carried to the eyrie to rear the young eagles, especially in summer. The nest can be found in a rocky crevice or a tree and is often used for decades by the breeding pair.
