In the vast wilderness of North America, one can find a remarkable assortment of wrens, comprising a total of 11 distinct species. Among these delightful songbirds, 8 have been documented in the picturesque province of British Columbia. Out of these 8 wren species, 7 are considered regular residents, while 1 species is considered an accidental visitor.
Throughout the year, a handful of wren species grace the landscapes of British Columbia. The Pacific Wren, Bewick’s Wren, Marsh Wren, Canyon Wren, and Rock Wren are permanent residents in the region. Meanwhile, the House Wren pays a summer visit, while the Winter Wren and Sedge Wren can be spotted during specific periods.
