The breeding season for these warblers varies from year to year, but can be seen to average from around September to January. The nest style produced is the enclosed pendant, very similar to that of the grey warbler. The female birds are the sole nest builders, and incorporate mosses, lichens, leaves, bark, feathers, small twigs and spider webs into the nests. The nests are also seen to be lined with soft feathers. The location of the nests differs depending on the island. Nests on the largest island tend to be hanging freely in the open and in gaps of vegetation, while nests on the surrounding islands are in dense foliage.
