Abstract. The aim of this study was to evaluate the influence of breeding units and two housing systems on the reproductive effects of cockatiels (Nymphicus hollandicus). The study was taken in an amateur breeding in the Masovian voivodeship in 2013. The material of the study was 10 pairs of cockatiels (Nymphicus hollandicus), half of which was bred in an aviary gregarious system, the rest of the birds was kept indoor in individual cages in pairs. The analysis of the breeding work is based on indicators: the number of eggs, the number of chicks reared and demises of birds in the two systems of breeding. The observed pairs of cockatiels characterized good reproductive indicators. However, the significant differences were found between the systems of rearing. All pairs had 2 clutches per year, but at the end of the breeding season the birds kept in the aviary reared a total number of 44 chicks. In comparison, the birds kept in individual cages reared only 22 chicks.
