Photographs of the three taxa included in this study and their distributions in New Guinea and Australia. Within the White‐shouldered Fairywren, female crown color is either brown or black in different subspecies, while males remain similarly ornamented black in all subspecies. In Red‐backed Fairywrens, male crown feathers are black in nuptial plumage, but females and males in the nonbreeding season have brown crown feathers. See text for more details. Gray regions of the map refer to other populations of WSFW not included in this study (Rowley & Russell, 1997); ranges based on BirdLife International and Natureserve (2013)
