Bewick's wren
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 in honour of his friend the engraver Thomas Bewick. Bewick's wren is now the only species placed in the genus Thryomanes that was introduced by the English zoologist Philip Sclater in 1862.
The Socorro wren was formerly also placed in Thryomanes, but is now known to be a close relative of the house wren complex, as indicated by biogeography and mtDNA NADH dehydrogenase subunit 2 sequence analysis, whereas Thryomanes seems not too distant from the Carolina wren.
Fifteen subspecies are recognised of which two are now extinct. Subspecies can be distinguished by the small differences in the color of the dorsal feathers but this can be difficult for museum specimens as the colors tend to change after a few years of storage.
Bewick's wren has an average length of 5.1 inches (13 cm) an average weight of 0.3 to 0.4 ounces (8–12 g), and a wingspan of 18 cm. Its plumage is brown on top and light grey underneath, with a white stripe above each eye. Its beak is long, slender, and slightly curved. Its most distinctive feature is its long tail with black bars and white corners. It moves its tail around frequently, making this feature even more obvious for observers.
Juveniles look similar to adults, with only a few key differences. Their beaks are usually shorter and stockier. In addition, their underbelly might feature some faint speckling. Males and females are very similar in appearance.
Bewick's wrens, like many wrens, are very vocal. Both females and males make short calls while foraging and both use a harsh scolding call when agitated. Males also sing in order to attract mates and protect their territory. The song is broken into two or three individual parts; one individual male may exhibit up to twenty-two different variations on the song pattern, and may even throw in a little ventriloquism to vary it even further. A male wren learns its song from neighboring males, so its song will be different from its father's.
