Pretty, medium-sized tetraka. Green back, gray head, and rich yellow underparts. Rare and localized Madagascar endemic that is found in a handful of forest patches in the southwest. Most often seen in the understory of western deciduous forest. Often in pairs, small flocks, or mixed-species flocks. Call is a series of silvery, sputtered “spit” notes. In its small range, separated from Spectacled Tetraka by its brighter underparts, gray head, and pale eye-stripe. Much smaller and more brightly colored than Long-billed Bernieria.
