The streak-capped antwren (Terenura maculata) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Argentina, Brazil, and Paraguay. The streak-capped antwren is monotypic. It shares genus Terenura with the orange-bellied antwren (T. sicki); the two are sister species and may form a superspecies.
The streak-capped antwren is 9 to 10 cm (3.5 to 3.9 in) long; one individual weighed 6.5 g (0.23 oz). Adult males' crown, nape, and upper back are streaked black and white. The rest of their upperparts are tawny to chestnut with some yellow mixed in on the rump; they have a hidden white patch between the shoulders. Their wings are black with pale yellow edges on the flight feathers (tawny on the tertials) and white tips on the coverts. Their tail is olive-gray. Their throat and upper breast are white with black streaks, their lower breast yellow with black streaks, and their belly and undertail coverts unstreaked yellow. Adult females are much like males, though paler overall. The white streaks on their head and nape have a pale buff tinge and the streaking on their underparts is less... Wikipedia →
