The crown and nape of adults of the nominate subspecies are rich dark brown that becomes progressively more reddish to the rump; the lower back has obscure bars. Their tail is reddish brown with darker bars. They have an off-white supercilium, a darkish brown eyestripe, cheeks mottled off-white and dark gray, and a blackish malar stripe. Their throat color ranges from whitish to pale buff; their chest is reddish buff and the belly a deep rich buff. Voice: Both sexes of the long-billed wren sing, sometimes alone and sometimes in duet. The songs are "loud and varied".

Stripe-breasted Wren

Cantorchilus thoracicus

Small18 gShrubland

The stripe-breasted wren is 11.5 to 12.5 cm (4.5 to 4.9 in) long and has a mean weight of 17.6 g (0.62 oz). Adults have a gray-brown crown, dark umber shoulders, back, and rump, and a dull blackish tail with buffy bars. Their face and sides of the neck have white streaks over a blackish base. Their throat and chest have black, white, and gray lengthwise streaks that stop abruptly at the plain olive-brown lower belly. Juveniles' upperparts are more russet than the adults' and the throat and chest have grayish brown, white, and dusky stripes. Voice: The stripe-breasted wren has two very different song types. One, which is apparently sung only by the male, is " a uniform series of whistles on one note" similar to that of some small owls. The other, sung by both sexes antiphonally, is "a cheerful series of liquid bubbling whistles." The species also has a variety of calls.
