Abstract:
This paper deals with the nesting of the House Sparrow on the basis of observations of 271 nests, mainly from South Poland. The situation (height and type of site), shape, and size of the nests, which the authors have classified in several groups according to the conditions of the site, as well as the material used for nest building, are discussed in succession. Great adaptive capabilities of the House Sparrow in respect of nesting are demonstrated and its nest construction is compared with that in other species of the family Ploceidae.
