 abstract={The study was carried out in two nature reserves in Warsaw (central Poland) in 1992-1995. Following aspects of Dendrocopos major nest hole's localisation are describing: tree species, height above the ground, tree trunk girth, condition of tree, tree fragrnent (in which nest was located) and entrance's exposure. Near all nest's parameters were different between two study areas what suggest that Great Spotted Woodpecker is quite indiscriminate in nest site selection.},
