From time to time we have the local Adelaide sub species of the Crimson Rosella in our garden here in Murray Bridge. This morning I observed two of them in the mallee scrub at the back of our house. They were in the company of the resident Mallee Ringneck parrots until they flew off.
Adelaide Rosellas are found in the Mt. Lofty Ranges and mid north of South Australia, as well as suburban Adelaide. The Crimson Rosellas are much brighter in colour (see photo below) while the Adelaide sub species has a washed out orange colouring on the front feathers. Throughout their range there is considerable colour variation in the intensity of the orange.
Here in Murray Bridge, some 75km south east of Adelaide, this species is near the eastern edge of their range. Consequently I only observe them several times a year. Normally I have to go 10-15 kilometres to the west to see them on a regular basis.
