In birds, singing behaviours play a critical role in mating and territory defence. Although birdsong can signal individual quality personality, very few studies have explored the relationship between personality song characteristics, none has investigated this females. Here, we examined relationships complexity two ecologically relevant traits (exploration aggressiveness) wild superb fairy-wrens ( Malurus cyaneus ), species which both sexes learn to produce complex songs. First, assessed males females (including juveniles) by quantifying their exploration behaviour (novel environment test) aggressiveness (mirror stimulation during short-term captivity. After birds were released, recorded songs over several months assess variation (i.e. element types per syllables song) relation personality. Regardless of sex or life stage, individuals that more exploratory had song. Additionally, aggressive produced with fewer syllables, fledglings, but not adults, Our study supports idea male female advertise when singing, may be important for mate choice.
