Guide to Boreal Birds
Perching Birds Overview
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.
Description
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.
Voice
A high-pitched, varied, and rapid series of musical trills and chatters; call note an explosive kit! or kit-kit!
Nesting
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.
Habitat
Dense tangles and thickets in coniferous and mixed forests.
