The Great Return: Observing the Common Crane in Wallonia
Every year, at the end of winter, a striking spectacle unfolds in the Belgian sky. The Common Cranes (Grus grus) begin their prenuptial migration, leaving their winter quarters in Spain and southern France to reach nesting sites in Northern Europe. Wallonia, and more specifically the Hautes Fagnes and the Virelles pond, is a crucial stopover for these long-distance travelers.
Where and when to observe them?
The optimal observation window extends from late February to mid-March. The birds travel by day, often forming those famous "V" shapes in the sky that can be seen from very far away. Their trumpeting call, carrying for several kilometers, is often the first sign of their passage.
- The Virelles Pond (Chimay): A major stopover site where the cranes land to rest and feed in the surrounding fields.
- The Fagne and the wetlands of the Hautes Fagnes: Flights regularly cross this region. Positioning yourself at the Baraque Michel viewpoint can be rewarding on a beautiful windy day.
- The agricultural plains of Hainaut: Large plowed fields are popular dining spots for their search for worms and leftover corn.
Tips for successful observation
Observing cranes requires a bit of patience and preparation. Here are my tips as an amateur ornithologist:
- Equip yourself with good binoculars: An 8x42 or 10x42 magnification is ideal for this type of medium to long-distance observation. Brightness is crucial in the often grey early spring weather.
- Check live migration maps: Sites like Observations.be allow you to follow sightings in near real-time and anticipate passages.
- Be discreet: If you spot a group on the ground, approach with extreme caution, using the terrain or hedges as cover. A disturbance can cause them to leave prematurely and waste their precious energy reserves.
- Note your observations: Participate in citizen science by entering your data on dedicated platforms. This helps to better understand and protect migratory corridors.
Witnessing the passage of the cranes is a moment of great emotion, a powerful reminder of the immutable cycles of nature and the incredible endurance of these birds. It is a privilege that we, as observers, must respect by minimizing our impact. Happy birdwatching! 🦢
