Résumé :	In March 2016, large flocks of Common Ravens were regularly observed in the neighbourhood of Bièvre (Western Ardennes). On March 21 2016, the place in which they meet each evening was discovered near Baillamont. Observations at this (pre-)roosting place revealed as many as 268 individual birds.These last few years increasingly large flocks of Raven have been seen in Wallonia. The Baillamont flock sets a new record – it is also one of the few roosting places that have been found. Several studies demonstrate the role of roosting places in this species as a place for exchanging information on the available food resources.
