Peruvian Wren Cinnycerthia peruana

An accomplished songster found in cloud forest along the east slope of the Andes in northern and central Peru. Some birds are almost entirely brown with faint black barring on wings and tail. Other birds have a variable amount of white on the face and forehead. Plumage is very similar to Sharpe’s Wren, which overlaps with it in northern Peru but is found mainly at lower elevations. In the area of overlap, voice is the best way to separate the two species. Peruvian Wren is often encountered in large family groups that move together through the lower and middle levels of the forest. Pairs sing elaborate duets consisting of rich whistles and trills. They also give rapid, frantic rattles when agitated.
