Résumé :	The data of first observation (FO) and start of birdsong (SB) respectively of 97 bird species in the community Kuhlen-Wendorf (county of Parchim, Mecklenburg-Vorp ommern) comprise the period from 1963 to 1968 and from 1977 to 2006. Beside the length of the period of investigation (more than four decades) it has to be emphasized that the data have been recorded by the same and only observer (ES) at all times. The large spectrum of species also includes some up to now only scarcely documented species of Non-Passerines.The medians of FO/SB reach from end of January to mid of May. Nuthatch Sitta europaea, Blue Tit Parus caerulus and Great Tit Parus major have the earliest FO/SB, Common Quail Coturnix coturnix, Icterine Warbler Hippolais icterina and Redbreasted Flycatcher Ficedula parva the latest. The later a species arrives or starts to sing the smaller is the range of FO/SB. Common Moorhen Gallinula chloropus, Stock Pigeon Columba oenas, Green Woodpecker Picus viridis and Water Rail Rallus aquaticus have the largest range, Icterine Warbler, Lesser Whitethroat Sylvia curruca, Corn Crake Crex crex, Garden Warbler Sylvia borin und Redstart Phoenicurusphoenicurus the lowest. The range of FO/SB is significantly lower in long distance migrants than in the other migration types.For 80 species the trend of FO/SB in Kuhlen-Wendorf is presented in form of smoothed curves, since the data of many species show no linear trend over the whole period of investigation. For example, the smoothed curves of 21 species support a striking flattening of a previous earliness or even a reversal towards a delay. An almost linear but not significant trend (0.05
