Bewick's Wren
Thryomanes bewickii
Bewick's wren has an average length of 13 cm (5.1 in) an average weight of 8–12 g (0.28–0.42 oz), and a wingspan of 18 cm (7.1 in). 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. Voice: 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.

Males alone sing, and have a repertoire of at least twenty different phrase patterns and on average, thirty two.
