Волоочко канадське Troglodytes hiemalis

Tiny, short-tailed, plain-brown wren with a huge voice. Subtly patterned, with indistinct pale eyebrow and diffuse dark barring on flanks and wings. Constantly keeps tail cocked at an angle. Found in a variety of forested habitats, but always prefers wetter areas with thick tangles, often around treefalls and moss. Darker, smaller, and shorter-tailed than House Wren. Incredibly beautiful song is a long series of musical whistles and trills; an unmistakable and common sound in northern forests. Call is a dry, low "chimp" remarkably similar to Song Sparrow.
