 The trills "hitchhike" on the predator's vocalization and the female splendid fairywrens, which have become more alert due to the predator calls, also respond more strongly to this type II song than when it's given without a predator call preceding it.Breeding occurs from late August through to January, though heavy rain in August may delay this.The nest is built by the female; it is a round or domed structure made of loosely woven grasses and spider webs, with an entrance in one side close to the ground and well-concealed in thick and often thorny vegetation, such as "Acacia pulchella" or a species of "Hakea".
