Résumé :	A comparison of Citril Finch populations at traditional postbreeding assembling sites in the northern Black Forest comfirmed a significant decline of the species. Possible reasons may be found in changes in land use due to the end of traditional pasturing and reforestation in the mountainous areas. Additionally a negative influence due to global warming and the linked change in vegetation composition and periods of growing is highly likely. Probable macroecological reasons such as the decline of populations in neighbouring areas (e.g. Alps) and the reduction of population exchange by dispersion may play an important role for the decline of Citril Finches at their northern areal boundaries as well.
