Unstudied. No nest containing young ever found.
Limited evidence suggests breeding coincided with onset of wet season (October/November) and lasted until January/February. Moult recorded from late January into April.
No precise information. Maximum life span at least nine years, as one individual ringed in 1974 was seen until 1983.
Spent most of time skulking silently in dense vegetation, making individuals extremely difficult to locate without use of tape playback.
Pairs shared a territory at least during the breeding season, when they would communicate with occasional soft “chak” calls. Only easily seen when a male delivered its staccato song from a prominent perch.
Apparent pre-disposition to set up territory in areas with abundant screw pine Pandanus cf. tectorius, in which the only active nest recorded was also situated.
