Assessment of reproductive parameters of privately bred ring-necked parakeets (Psittacula krameri)

Abstract

The aim of this study was to assess the reproductive parameters of privately bred ring-necked parakeets (Psittacula krameri). The study was carried out in an amateur breeding facility in the Masovian voivodeship in 2013–2017. Observations were carried out on four pairs of ring-necked parakeets kept year round in outdoor aviaries. The analysis was based on the following indicators: number of eggs laid, number of chicks hatched, and number of chicks reared from two broods each year. The reproductive parameters of the pairs of ring-necked parakeets were varied. There were marked differences between individual pairs of birds concerning both the number of eggs in the clutch and the number of chicks reared. Most pairs reared two broods each year. In the first year of observation, the birds reared eight chicks from 13 laid eggs, while in the last year of data collection they reared 11 chicks from 16 eggs.
