Abstract Recent evidence suggests that female ornaments can commonly act as signals. However, how signaling functions might be affected by the tendency for reduced ornament elaboration in relation to males is less well-understood.

Abstract Historically, bird song complexity was thought to evolve primarily through sexual selection on males; yet, in many species, both sexes sing and pressure may be broader. Previous research suggests competition for mates resources during short, synchronous breeding seasons leads more elaborate male songs at high, temperate latitudes. Furthermore, we expect male–female structure elaboration similar lower, tropical latitudes, where longer year‐round territoriality yield social pressures sexes. However, studies seldom take types of selective into account. We examined 15 populations nine‐fairy‐wren species (Maluridae), a Southern Hemisphere clade with female song. compared (in sexes) dimorphism latitude life‐history variables tied sex roles. Our results suggest that evolved part due males: were than low survival less provisioning. Also, independently songs: slower paced songs, although only synchronously populations. also found when parental care equal which provides strong evidence role similarity correlates similarity. Contrary Northern latitudinal patterns, higher, These can specific, favored contexts stronger selection. At the same time, associated appear favor structure.
