For years they were thought to be a recessive mutation and males and females were sold as splits. Prices averaged about $1,900 for the Rosies and nearly$1,500 for the splits. In 1977 the German aviculturist and well known breeder of mutations, Siegfried Bischoff, suggested that the Rosy Bourke is really a cinnamon mutation in which the yellow pigments are replaced by reddish pigments. Such a mutation should, of course, be sex-linked. His idea proved to be correct, and it is now generally accepted that the Rosy Bourke represents a sex-linked mutation. Though my own breeding results have substantiated the sex-linked nature of this mutation I should add that the Rosy Bourke also exhibits pied-like characteristics, i.e., no one Rosy Bourke looks quite like any other one. Some are nearly entirely rosy, still others show a substantial amount of melanin pigments. Eventually, I am sure, we will be able through selective breeding, to produce an all red or rosy-red Bourke.īreeding the Rosy Bourke produces few surprises if we recall the laws of sexlinked inheritance. Therefore, a normal split-for-rosy male paired with a normal hen will produce 25% Rosy offspring, all of which will be female. Another 250Jo will be normal females and the remaining males will divide up evenly into normal males as well as split Rosy males. Only test breeding will tell us which males are truly split.Ĭrossing a split Rosy male with a Rosy hen will produce 50% Rosies of both sexes. The other 500Jo will also consist of males and females but only the males will be split.įinally, a pairing of a male Rosy Bourke with a normal hen will produce 500Jo Rosy Bourke hens and 500Jo split Rosy males. This is obviously a very desirable combination. Rosy paired to Rosy will produce.The Red-rumped Parrot is a colorful bird species that are native to Australia. This small parrot is a popular pet among bird enthusiasts due to its striking appearance and engaging personality. This article will explore the Red-rumped Parrot’s physical characteristics, behavior, habitat, care, and breeding. We will also discuss the common health conditions and mutations that affect this species.
