    Habitat:

    The Western Rosella they are not very common. Found in variable densities in stands of eucalyptus and in many types of open forest habitats. They also attend camps with little trees, partially cleared farm fields and residual trees lining the fields of cereal or the sides of the roads. They tend to visit the gardens and freshly harvested fields. They occasionally enter the parks, gardens and golf courses.

    In areas close to the coast, the Western Rosella, without a doubt, they have benefited from the transformation of the dense woods on agricultural land. On the other hand, they were expelled from the Inland deforestation programmes on a large scale.

    The Western Rosella they suffer the aggressive competition Australian Ringneck (Platycercus zonarius) that shares the same habitat type.

    The Western Rosella they are sedentary birds. Usually, they live in pairs or in small groups, and it is very rare to find them in flocks. They are quiet and discrete, so very often go unnoticed when they feed in Earth or when they seek refuge in the trees.

    Around the houses, the Western Rosella they are very confident, coming into barns and corrals to feed on grain. Unlike other parrots, they have a stable flight consisting of multiple hits. Move over short distances, preferring to fly from one tree to another, instead of crossing open spaces.

    Reproduction:

    The nesting season runs from August to December.

    The nest is in the hole of a branch or in the cavity of a tree trunk. The couple often choose a eucalyptus wandoo the genus eucalyptus salmonophloia. The cavity must be deep enough and the Fund should be lined with a layer of sawdust.

    Before mating, the male courts to your partner. Leaning forward on his perch launching very specific cries. If the female agrees, responds in the same way.

    Sunset, generally, comprises of 3 to 7 eggs which are incubated during 19 days. The female is responsible for one incubation, but she pauses in the morning and in the afternoon to be resupplied by the male.

    Young are altricial, and do not fly far before reaching the age of 5 weeks.

    Food:

    They mainly eat seeds of grasses and other plants that are in stubble fields. They also feed on fruits, berries, Jarrah flowers (Eucalyptus marginata) and seeds of the Zamia Palm.

    Often in orchards where cause some damage.

Sometimes found in parks in Perth.
