In the higher rainfall far southwest corner of Western Australia, Red-winged Fairy-wrens are the only member of the chestnut-shouldered group of fairy-wrens to occur, replacing both the Variegated and Blue-breasted Fairy-wrens. Their northern limit is the valley of the Helena River just west of Perth, and on the south coast occur as far east as Two Peoples Bay just east of Albany. There is also an outlying population still persisting on Gingin Brook, NE of Perth. Red-winged Fairy-wrens were studied for many years down near Manjimup, so their life history is fairly well known.( Rowley,I., Russell,L., Brown,R. and Brown,M.
