The Winter Wren – Troglodytes hiemalis is a very small bird of the coniferous forests of North America. It is known to migrate in the winter although small numbers remain local in the western United States and Canada.
The winter wren nests mostly in coniferous forests, especially those of spruce and fir, where it is often identified by its exuberant song. It survives by eating insects and can remain in cold and even snowy climates by foraging for insects in bark and fallen logs.
At night, usually in winter, it often roosts in dark retreats, snug holes and even old nests. In especially cold weather it may roost with many individuals gathered together for warmth.
