Immediately after the reuniﬁcation of Berlin in 1990 the ‘Berliner Ornithologische Arbeitsgemeinschaft e. V. (BOA)’ decided to investigate the actual distribution and numbers of breeding birds of Berlin, and with that to close the artiﬁcial division of avifaunistic presentations since 1945. Between 1989 and 1999 (2000) numerous observers mapped all territories of rare species in the whole area of the city. For common species new data on abundances were put together ordered for habitat, total numbers predicted, and population trends over the last 25 years estimated based on existing former data.
From about 1850 to 2000 a total of 178 breeding species was mentioned for the recent area of Berlin (892 km2), of which, however, 27 species became extinct up to 1989. The remaining 151 species still document a high level of species richness of the city, which mainly is caused by extended forests and waters, and some other wetlands. For 80 of these species maps of territories are shown. A subdivision by trend is as follows: 21 are irregular breeders, 44 are slightly to strongly increasing, 43 are more or less stable, and 43 are slightly to strongly decreasing breeders. Main reason for negative developments are changes of land use, which serve for losses of special habitats. Comparing the situation of Berlin with that of Germany as a whole the breeding bird community of Berlin is less
stable. Most frequent species are: House Sparrow (Passer domesticus) (100 000 – 200 000 bp), Blackbird (Turdus merula) (35 000 – 70 000 bp), Blue Tit (Parus caeruleus) (37 000 – 55 000 bp). Spectacular newcomer in 2000 is the White-tailed Eagle (Haliaeetus albicilla).
