The song of the Winter Wren (Troglodytes hiemalis) is clear, rapid, and very high in pitch, often with notes beyond the range of human ears. The wren sings along at 16 notes a second, stringing beautiful, tinkling passages into long pieces. It sings over the sound of surf on remote Alaskan islands, where it nests on cliffs and rocky slopes near the shore.
Elsewhere it is most often a bird of the deep woods, nesting in the earth that clings to the roots of fallen trees, under standing roots, or in crevices between rocks. This wren species prefers coniferous and mixed forests with heavy undergrowth, often near streams, and wooded swamps.
