Small, energetic, sharp-billed warbler. Always shows strong striping on the underparts. Madagascar endemic that is found in rainforest, spiny forest, and scrub, and only very locally in dry deciduous forest. Often joins flocks with other small bird species. Song in the east is a long, sweet, up-and-down trill. Song in the west is a complicated series of high notes and lower trills. Larger and bigger-billed than other jeries, with dark legs and strong striping below. Smaller than Rand’s Warbler, with a greener back, a weaker eye-stripe, and streaking below.
