Breeding of Eastern Rosellas in European Climate Conditions
Baierlová, Nikola ; Ledvinka, Zdeněk (advisor) ; Zita, Lukáš (referee)
Summary
This work is aimed at parrot breeding of genus Rossella in Europe, in different climatic conditions than the conditions in the Southeast and South Australia where the birds come from. Here, you can find overview of their occurrence in nature, evaluation of biotope, feeding and information on breeding in human custody.
Eastern Rosellas (Platycersus eximius) live in pairs and each pair is very protective
of their own nesting teritory. Outside of the nesting season, Rosellas are moving around the land in small groups.
In nature, these parrots eat grain from grass or weeds, seeds from bushes, trees
and of course fruit.
The nesting season starts around february and lasts until august. In nature Rosellas nest in hollow trees, branches, tree stumps, columns, on top of fence post and even in rabbit holes.
The best option when it comes to breeding Rosellas, is an outside aviary, which best represents their natural habitat. European winter causes them little to no trouble, the same goes for severe frost, which allows for year-round stay in the outside aviary.
Rosellas have the similar eating habits as their parrot brethren, meaning sunflower seeds, millet, panic grass, canary and oat. An important supplement in their daily diet is green feed(ing), fresh fruit and vegetable, branches to nibble on, mineral substances, and fresh drinking water. During the nesting season and while with young, it is necessary to feed
the birds an egg mixture, it is an important source of protein.
Breeding of Rosellas is fairly effortless, they can easily nest even in small spaces. Ideal size of their bird house would be 25 x 25 x 60 - 70 cm with a fly-in entrance of 7 - 8 cm. It is necessary to hang the bird houses as high as possible in the protected part of aviary. Female lays 5 - 7 white colored eggs, on which she sits 21 - 22 days. Young birds leave
the nest in age between 28 - 35 days and then, are are partly fed additional 10 - 14 days by
the male.
Among the most frequent diseases of this species of pet birds belong those non contagious, e.g. hypovitaminosis, uricosis and, furthermore parasitical ones and pathogens as well as other contagious diseases or feather abnormalities, such as the so called French defeathering.
Breeding of Rosellas does not require an experienced breeder. With proper care, Rosellas can live up to 25 - 30 years and remain fertile their whole lives.

Rosela breeding species in European Climate Conditions
Hanzlíková, Dana ; Zita, Lukáš (advisor) ; Ledvinka, Zdeněk (referee)
Summary
The bachelor thesis focuses on breeding of rosellas. The genus Rosella belongs to the family Psittaculidae and to the order Psittaciformes.
The first part of the thesis deals with rosella´s wildlife. Rosellas are Australian endemics, they can be found in rainforests, sclerophyl and savannah forests. As a result of human influence on changing their environment, they adapted to the agricultural landscape. The nesting biology is similar for all genus. The breeding season starts in spring when males court females. Couples choose hollows inside trees for nesting, the most frequently in the eucalyptus near to a water source. Only the female sits on eggs, the male takes care of her for the whole time. Both parents take care of hatched nestlings.
In the next part, there is discussed the issue of rosella´s nutrition. The correct feeding is important for parrot´s comfort and health. The composition of the appropriate feed is derived from their natural food.
In the next part, there are summarized current knowledge of breeding rosella. It is recommended to breed only one couple of rosellas, not to combine them with other species at all because of aggressive behaviour of this genus. The breeding in outdoor aviaries is perfect for rosellas in human care. They need enough space for flying. The reproduction is suitably supported by the outdoor environment. Most species are adapted to the European climatic conditions and tolerate cold periods. They will be satisfied with the shelter which is not needed to be heated and where they can hide from frost, rain and wind. Rosellas love water, they should have a bowl for this purpose. Mostly they nest without comlications, the problem can come with creating a suitable breeding pair. Rosellas are not too demanding in the case of nesting boxes.
The next part highlights the importance of hygiene and disease prevention. There are mentioned the most common diseases and ways to take care of sick parrots.
The representatives of the genus rosella are characterized in the last part of the thesis. The thesis concentrates on the western rosella and other less common species.
