The species is distributed over nearly the entire country and reaches its highest densities in wooded areas, especially on richer soils. Since the 1970s, the breeding range has expanded into the reclaimed polder Zuidelijk Flevoland and open farmland in the west and north of the country, due to new plantations. Numbers elsewhere have grown as well, partly because of changes in forest undergrowth (increase of bramble and nettle) stimulated by atmospheric deposition and providing good nesting cover. The breeding population is estimated at 550,000-600,000 bp in 1998-2000.
