A medium-sized yellowish-brown bird with a long tail. Endemic to the island of Moheli in the Comoros. Found in remnant montane forest scraps, as well as locally in secondary habitat down to low elevations. Feeds mainly at middle levels and in the lower part of the canopy. Occurs alongside Madagascar Brush Warbler, but rarely skulks in the undergrowth, and can be further distinguished by its shorter tail and its paler and plainer yellowish coloration, without strong streaking on the breast. The song is a series of scratchy notes and squeaks that is reminiscent of a sunbird, though lower-pitched. The calls are “chek” and “veet” notes often given in a series.
