Verhalten

The stripe-breasted wren usually forages in low dense vegetation. Its diet has not been fully documented but is known to include insects and spiders.<p>The stripe-breasted wren nests between March and July in Costa Rica. Both sexes build the nest; it has two chambers and is draped over a branch; a downward-facing entrance is in one chamber. It is made of plant fibers covered with moss and is typically between 1.5 and 6 m (4.9 and 19.7 ft) above ground. The clutch size is two or three.<p>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.
