The distribution map is somewhat inflated by the erratic annual breeding pattern, as the species switches easily to new suitable breeding sites. Most colonies are situated nowadays in sand pits. As large-scale digging has replaced small-scale activities, some range contraction since the 1970s is obvious, whereas numbers per colony have increased (in 1998-2000 at 9 sites more than 500 bp, maximum of 1564). The breeding population decreased from 20,000-25,000 bp in the 1960s to 5000-8000 bp in 1974-78 and even 4000 in 1984-85. At the end of the 1980s and, especially, in the 1990s, numbers have recovered to 18,500-32,000 bp in 1998-2000, stimulated by favourable wintering conditions in the Sahel area and an increase in construction works.
