Résumé :	For the first time an estimation of numbers for all Bavarian breeding birds is given, together with trends and changes in abundance, based on data from 1975 to 1999. Regular breeding birds number 203, with an additional 11 casual breeders and 11 neozoons. In the time span investigated, 8 regular breeding birds became extinct, whereas 6 species were declared new or repetitive regular breeders. Within large birds the portion of rare and very rare birds (60%) exceeds such of common ones (40%), contrary to small birds with 44% (at least rare) and 56% (common) respectively. Positive trends in abundance are more frequent in large birds (29%, negative: 22%) as compared to small birds (11%, negative: 24%). This paper, together with the "Atlas of breeding birds of Bavaria", "Red List of breeding birds of Bavaria" and "Annotated species list of all Bavarian breeding birds" (all in preparation) will form a sufficient base for further bird conservation work from 2004 onward.
