As the majority of birds on the island who live in a small area, to the Green Rosella It is cataloged as sedentary. However, the specimens that live in altitudes of up to 1500 meters in the Alpine regions, they make altitudinal movements and approaching at low altitude towards the coastal regions in winter season.
