Influence of cliff-climbing on the rupicolous birds in the Upper-Meuse.
The Belgian Upper-Meuse is a region rich in calcareous cliffs, the height of which may reach 100 m; nearly a quarter of these are intensively frequented by climbers. The nesting effectives of the three following species were counted in the spring of 1987 : Jackdaw, Kestrel, Stock Dove. The disturbance caused by climbing appears to be very little in the case of the Jackdaw, but generally keeps away the Kestrel. The evolution is worth following up in view of the important increase in the practice of climbing.
