We will also discuss the common health conditions and mutations that affect this species. This article will explore the Red-rumped Parrot’s physical characteristics, behavior, habitat, care, and breeding. This small parrot is a popular pet among bird enthusiasts due to its striking appearance and engaging personality. Rosy paired to Rosy will produce.The Red-rumped Parrot is a colorful bird species that are native to Australia. This is obviously a very desirable combination. 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. ![]() 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. Another 250Jo will be normal females and the remaining males will divide up evenly into normal males as well as split Rosy males. Therefore, a normal split-for-rosy male paired with a normal hen will produce 25% Rosy offspring, all of which will be female. 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. Some are nearly entirely rosy, still others show a substantial amount of melanin pigments. 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. His idea proved to be correct, and it is now generally accepted that the Rosy Bourke represents a sex-linked mutation. Such a mutation should, of course, be sex-linked. 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. Prices averaged about $1,900 for the Rosies and nearly$1,500 for the splits. For years they were thought to be a recessive mutation and males and females were sold as splits. The genetic inheritance of the Rosy Bourke became the subject of great controversy among European aviculturists. These offsprings formed the nucleus of a beautiful new mutation: the Rosy Bourke. This pair produced four normal looking males and three hens which were covered with rosy feathers over their entire back. He had paired a newly acquired normal male with a hen which originated from his cinnamon stock. The first Rosy Bourkes appeared in the Dutch aviaries of Mr. Some blue remains on the rump and on the secondaries, but the blue frontal band on males as well as the intense blue of the underside of wings are missing. Only the tail, the primaries, and a few of the secondary wing feathers remain dark. Most color photos can't do justice to the soft rosy reds which cover almost the entire body. ![]() One of the newest mutations is the stunningly beautiful Rosy Bourke. May, 1977) and Erhart elaborated on the differences between the genetic inheritance of the sexlinked Cinnamon and the recessive-breeding Yellow Bourke (AFA Watch bird, Oct. Smith has already reported on the Yellow Bourke (AFA Watchbird, Apr. One other reason for the Bourke's continued popularity is the emergence of several attractive mutations. ![]() All Bourkes become very active when darkness approaches and they may still be feeding on the aviary floors when other birds have already retired for the night. ![]() It is also a very friendly and relaxed bird often acting more like birds which have been hand raised. Like other grass parakeets, the Bourke is a quiet and gentle bird, never destroying any part of your aviary. The males in particular are very showy specimens. It's colors may not rival those of many other parrots but the soft shades of blue, brown and red are indeed very attractive. The Bourke Parakeet still remains a very popular bird in our aviaries.
