Tek Renkli Tapakola Scytalopus unicolor

Small, gray bird found only in the western Andes of northern Peru. Adult is plain gray, lacking any black or brown barring on lower underparts. Young birds are browner and heavily scaled with gray and buff. Inhabits forest understory and heard much more often than seen. Listen for soft frog-like notes that are given alone or in a series of accelerating bursts.
