The plumage of the eastern rosella is especially vividly coloured — red and yellow and blue and green and black. Despite this bold colouration, when rosellas are feeding on the ground among the grass or perched among the foliage in the treetops they can be very difficult to see, often seeming to disappear completely into the background. Despite their bright colours, their plumage is patterned so that it creates an extremely effective camouflage which assists the birds in avoiding detection by potential predators. |
