The distribution is concentrated in the (semi)-open grasslands of the eastern and southern Netherlands, on sand as well as peat or (more locally) clay. The majority nowadays inhabits farmland whereas traditional habitats as coastal dunes, heaths and peat moors have lost much of their significance (for reasons that are not fully understood, although poor reproduction plays a key role). The switch from natural habitats to farmland took place in the 1980s and 1990s. Recent figures suggest that the colonisation of farmland has reached its maximum. Population: 6400-7400 bp in 1998-2000 (3000 in 1973-77).
