Résumé :	On 14(th) August 2007 a first year Thrush Nightingale was caught and ringed in the moors near the village of Betzigau (47 degrees 44' N; 10 degrees 23' E; 710 m NN, Swabia, Bavaria). This lies within the seasonal distribution of 13 other records documented from Bavaria since 1900. The seasonal pattern of occurence in Bavaria, Austria and Switzerland shows two clear-cut periods of migration (middle to end of May and mid-August to early September). It appears that the few records do not reflect the real occurence of this secretive and -especially when not singing -inconspicuous species outside its breeding range. Field ornithologists should take greater care. The characteristics of the Thrush Nightingale and the Common Nightingale are both complex and variable. Hybrids between the species occur. Nevertheless, the two species can be distinguished with a high degree of confidence in most cases. All records should be documented exactly and submitted to the Bavarian Records Committee.
