All somewhat passionate Belgian birders have been on this platform as it is the only place in the country to see Black Grouse. Although there is also a dark side as this population is on the brink of extinction. In 2016 less then 5 individuals remain, but since then conservation efforts are made as some Swedish birds are relocated to the area between 2017 and 2021 (around 20 individuals per year). They remain year-round on this location, altough the best months to see them are by far late February, March and April. During these periods it's possible to observe the courtship behavior of the males and often the females sit quite high in the trees. The best chance to see them is very early in the morning at dawn.
Even if you don't manage to see them it's a very good location to see Hen Harrier , Great Grey Shrike , Common Raven , Red Kite , Common Crane (only during migration periods, they do not breed in Belgium), Bullfinch, Red-backed Shrike , Tree Pipit and Black Stork.
A lot of parking space is available at 'Le signal the Botrange'. Click on the P in the map to get directions. It's possible to walk around the area, although the best place to observe birds is at the wooden platform.
