Résumé :	In Central Europe all the different types of landscape are more or less totally exploited or will be influenced by human impacts in near future. Short-term processes rather than Longterm steady states will therefore influence bird numbers. This means a challenge far field ornithology and nature protection as well. To understand the situation of birds modern aspects of population biology and results of adequately designed monitoring should substitute or supply single counts or short-term samples. Single records or episodes on birds and their behaviour have to be interpreted more critically considering the possibilities of success (individual fitness). The situation of birds in urban environments may be described non predictable changes due to socio-economic purposes. Declines of House Sparrow and Cre-steel Lark are actual examples for the problems involved. Also technogenic habitats are mostly very short-lived. Consequences of single habitat manipulations on bird populations are fare mare complex than considered by most planning contributions of conservationists. An adequate network of protected areas may be the only way to conserve populations of many species.
