Odd, warbler-like, long-tailed and long-billed tetraka. Madagascar endemic that is the only tetraka regularly found in spiny forest. Mostly skulks in the understory, but will sing from an open perch at the top of a tree. Song is a sputtering trill that is sometimes followed by a series of lower “chup” notes. Larger, longer-tailed, and longer-billed than jeries. More greenish than Subdesert Brush Warbler, with white tips to the tail, and without fuzzy breast streaks.
