Size: The average size for the Crimson Rosella is 14 inches (36cm) while the Golden Mantles are smaller at about 12 inches (30cm).
Diet: A good Rosella diet should consist of canary seed, a mixture of millets, sunflower and safflower. Most people will use a Cockatiel seed mix with added Canary seed. They also enjoy fresh fruits & veggies such as apples, blackberries, oranges, cucumbers, sweet potato and mango. Sprouted seeds, kale, boiled egg can also be offered. I find that our Crimson Rosellas tend to totaly devour the fresh foods while the Golden Mantles will take bits and pieces leaving leftovers.
General Care: These birds love to bathe and should be provided fresh water to do so.
Compatibility: Males are very much aggressive towards other males exspecialy in the presence of a hen. Young birds should be seperated from the parents as soon weaned to prevent parental aggression. If you house pairs seperatly in side-by-side flights you may want to place solid dividers between the flights as this will help a great deal with aggression. It is not wise to house this spieces with others.
Housing: Rosellas do best in an aviary setting or long flight cages as they are avid flyers. Single pets can be housed in med. size parrot cages as long as they are allocted time each day out of the cage.
Song: Though they do not have a true song they do have several melodious calls. Similar to a louder Red Rump it is much more pleasent then the shrill & harsh sound of Conures, Cockatoos or Macaws. Rosellas are not known for much talking ability but they can mimic whistles and songs.
Breeding: The Rosella breeding season normaly ranges from October-March. Establishedpairs can prove prolific producing on average two-three clutches per season. When courting the male will bow forward low on the perch while sounding out the mating calls. If approved the hen will do the same and they can often be seen feeding each other before mating. The hen will lay and incubate 3-7 eggs for 20 days before they begin to hatch if fertile. After hatching chicks will leave the nest at about 6 weeks old. Some breeders prefer to pull babies at 2-3 weeks old to handfeed. This will give the parents more time to begin on another clutch. Handfed Rosellas can still be a bit flighty and care should be taken to insure the wings stay clipped to avoid them harming themselves. They will also need daily attention to remain tame or will quickly revert.
