Bewick's wren (Thryomanes bewickii) is a wren native to North America. It is the only species placed in the genus Thryomanes. At about 14 cm (5.5 in) long, it is grey-brown above, white below, with a long white eyebrow. While similar in appearance to the Carolina wren, it has a long tail that is tipped in white. The song is loud and melodious, much like the song of other wrens. It lives in thickets, brush piles and hedgerows, open woodlands and scrubby areas, often near streams. It eats insects and spiders, which it gleans from vegetation or finds on the ground.
Its historic range was from southern British Columbia, Nebraska, southern Ontario, and southwestern Pennsylvania, Maryland, south to Mexico, Arkansas and the northern Gulf States. However, it is now extremely rare east of the Mississippi River.
In 1827, the American ornithologist John James Audubon included an illustration of Bewick's wren under the binomial name Troglodytes bewickii in his The Birds of America. In the companion Ornithological Biography, published four years later, Audubon explained that he had shot the specimen near St. Francisville, Louisiana in 1821 and had chosen the specific epithet bewickii...

GBIF citizen-science records
It is estimated from how often the Bewick's Wren is recorded against all the birds logged in Grand Canyon National Park (354 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
