The Wallcreeper Tichodroma muraria is a rare wintering bird in Wallonia but is probably under detected. Specific research allowed finding a bird in Dinant on 30th December 2014. The wintering of that bird was followed until its departure on 8th April 2015. The wintering range extended on a 2km-part of the Haute-Meuse valley including natural cliffs and buildings including the citadel. This article describes visited places, the roosting site and partial moult to the breeding plumage. A second wintering bird was found on 7th February 2015 in a quarry in the Ourthe valley and stayed until end of March. This is the first reported case of a simultaneous wintering of two Wallcreepers in Wallonia. A better prospecting of suitable sites could bring out wintering birds more regularly in Wallonia.
