Online seit 5 Mai 2015 Abstract Birds of the river valley Schwechat in the municipality Traiskirchen (Lower Austria). The river Schwechat runs 7.2 km through the municipality of Traiskirchen (Lower Austria), south of Vienna. 54.2 ha of the 120 ha sized study area are protected by law. In this nature conservation area the river Schwechat is predominantly unregulated. Ca. 70 ha of the study area is dominated by hardwood alluvial forests, while the rest consists of different habitats (mainly water bod‐ ies, gallery forests, sand and gravel banks, tall forbs vegetation and fallow land). 104 bird species have been found between spring 1993 and January 2015. For 53 species breeding is confirmed, probable or possible. 51 species were only noticed as wintering, migrating or feeding guests. Within the borders of the protected area 101 species and out‐ side 63 species have been detected. Two major guilds of bird species have been found: one is typical for floodplains and the other for structural complex broad‐leaved forests. The diversity and density of bird species using nest‐holes for breeding is high. Seven different woodpecker species were found, at least five of these are definitely or probably breeding.
