I got very excited about a fairywren I saw in the Perth hills recently. For a 
while I thought I had the blue form of White-winged Fw in a place they haven’t 
been recorded. A close look at my photos showed it wasn’t a brilliant white 
wing I’d seen but the back - usually rufous or chestnut in  Red-winged Fw. I 
assume that bird, which was associating with a family of Red-winged Fw, was a 
leucistic individual, and had none of the rufous. / chestnut pigmentation 
usually present in the species.
