Résumé :	The cultivation of the Crau's natural steppe, the "coussoul", progressively gave place to a mosaic of pastoral and agricultural habitats, especially in the north of the plain. The consequences of these landscape changes for steppe birds are complex: in addition to the reduction and fragmentation of the original habitat, new "modified" habitats, more or less suitable, have developed at the periphery. In this work, I illustrate different aspects of the complementarity between the coussoul and modified agro-pastoral habitats for the little bustard Tetrax tetrax. At the scale of the year-cycle, a complementarity appears between, on the one hand pastoral habitats (coussoul, fallows and grazed crops), with a permanently short sward (
