Field notes
- It was considered the same species as the Winter Wren and Eurasian Wren until split in 2010 based on DNA and vocalization differences.
- Gram for gram, its song contains ten times more notes and significantly more sound energy than the vocalizations of a crow.
- The bird frequently cocks its short tail nearly vertical and bobs its entire body when agitated or curious.
- Males often construct multiple 'dummy nests' within their territory to provide options for the female or to deceive predators.
- It primarily forages like a mouse, creeping through dense undergrowth and root tangles to find insects and spiders.
Habitat
Old-growth and mature coniferous forests, typically near streams, mossy logs, and dense woody debris.
Range
Western North America, ranging from coastal Alaska down to central California and inland to the Rocky Mountains.
