The Winter Wren is a small, 4” to 4 ½”, round, dark wren, smaller than the more common Bewick’s Wren. It has a very short tail, a light line over the eye, and brownish, heavily barred flanks. It often bobs and bows.
Found in coniferous forests and woodland underbrush, it is a year-around resident on the Pacific Coast from California to Alaska. It breeds in northern U.S., southern Canada, and the Alaska coast.
Its song is a rapid succession of high tinkling warbles and trills, and often ends on a very high, light trill. The song lasts about 5 seconds, and is repeated 4 to 6 times a minute. Its low double-call note, tick-tick, is distinctive.
