Abstract
Five raptor species were recorded as breeding in the city of Wrocław (293 km<sup>2</sup>) during the years 2002-2010: <em>Falco tinnunculus</em> (2.4 pairs per 10 km<sup>2</sup>), <em>Buteo buteo</em> (4.1 pairs/10 km<sup>2</sup> of wooded area), <em>Accipiter gentilis</em> (3.1 pairs/10 km<sup>2</sup> of wooded area), <em>Accipiter nisus</em> (1.6 pairs/10 km<sup>2</sup> of wooded area), <em>Circus aeruginosus</em> (0.2 pairs per 10 km<sup>2</sup>). All these species have increased in numbers over the last 20-30 years, both in the inner and outer zone of the city. <em>Falco tinnunculus</em> is a well-established raptor in the inner part of the city, while <em>Accipiter nisus,</em> <em>A. gentilis, Buteo buteo</em> started to infiltrate to the inner zone. In the last 70 years, a few cases of nesting were recorded for four other raptor species in Wrocław: <em>Milvus migrans, Milvus milvus, Pernis apivorus </em>and <em>Falco subbuteo, </em>but none of them was recorded in the inner zone of the city.<em> </em> Abundant and stable food supply (small mammals, columbids, corvids and small passerine birds), and freely available nesting and perching sites may contribute to this success.
