The Crimson Rosella is relatively easy to see as it forages on the ground or among the leaves of eucalypts, with its spectacular combination of deep-crimson, royal-blue and black plumage. However, not all Crimson Rosellas look the same. Along the Murray River, Crimson Rosellas aren’t crimson at all — they are yellow, black and blue, with the yellow feathering replacing the crimson plumage. In southern South Australia they differ again, being roughly intermediate between crimson and yellow, with varying amounts of red and yellow in their plumage.
