Winter Wren

Winter Wren
Troglodytes troglodytes
Perching Birds | Family: Wrens, Troglodytidae

An estimated 43% of the species' North American population breeds within the Boreal Forest.



This wren moves like a mouse, creeping through the low, dense tangle of branches covering the forest floor. Its nest is among the hardest to find; even when an observer has narrowed the search to a few square feet, he must sometimes give up, so cleverly is the nest concealed. The Winter Wren's song, when recorded and played back at half- or quarter-speed, reveals a remarkable blend of halftones and overtones all sung at the same time.


4-4 1/2" (10-11cm). A tiny, dark brown bird with a very short tail, narrow pale eyebrow, and heavily banded flanks and belly. See House Wren.


A high-pitched, varied, and rapid series of musical trills and chatters; call note an explosive kit! or kit-kit!


5-7 brown-speckled white eggs in a bulky mass of twigs and moss, with an entrance on the side, lined with softer material and often concealed among the upturned roots of a fallen tree.


Dense tangles and thickets in coniferous and mixed forests.


Breeds from Alaska and British Columbia east through southern Canada to Newfoundland, and south to California, northern Idaho, Great Lakes region, and southern New England; also in mountains to Georgia. Winters across much of southern United States south to southern California, Gulf Coast, and Florida. Also in Eurasia.
