Assessment of reproductive parameters of privately bred zebra finch (Taeniopygia guttata)

Abstract

The aim of the study was to assess breeding of zebra finches kept in a flock in an amateur indoor aviary. The research was carried out at an amateur breeding facility in the Masovian Voivodeship in 2014-2018. The subject of the study was 5 pairs of zebra finches (Taeniopygia guttata) kept in an indoor aviary. Analysis of breeding was based on the following parameters: number of eggs laid, number of chicks hatched, and number of chicks reared from two broods each year. The reproductive parameters of the zebra finch pairs were varied. There were differences between individual pairs of birds for both the number of eggs laid per clutch and the number of chicks reared. Most of the zebra finch pairs had very good reproductive parameters; only a pair consisting of two albino individuals did not rear any offspring in any of the breeding seasons.

Papillary Cystadenocarcinoma in a Budgerigar (Melopsittacus undulatus)

“…Although most parrots are at risk, budgerigars have stable populations and are not considered endangered (Kalmar et al, 2010). This gregarious parrot has a short breeding cycle; its lifespan is 10-15 years (Kubiak, 2020;Banaszewska et al, 2014). Adenomas and cystadenomas are benign neoplasms derived from glandular epithelium.…”
