Résumé :	The need for clear distinctions between individual populations and subspecies of a study species is becoming more and more apparent in many fields of basic science and in nature conservation. The necessity to focus fieldwork more on the various adaptations of these “units” is apparent in the face of a rapidly changing anthropogenic world. One of the aspects of comparative ecology which seems to have been neglected considerably thus far is the often striking differentiation of mountain and lowland populations of our birds. The case of the Willow Tit complex exemplifies this, as its respective Central European subspecies currently show marked differences in population dynamics which are diffcult to explain. The paper describes some of the known differences in altitudinal adaptations, points to the lack of relevant studies and urges to consider the important conservation implications comparative ecological studies of these populations might have
