Stripe-chested Antwren

The stripe-chested antwren is 9 to 11 cm (3.5 to 4.3 in) long and weighs 8 to 9.5 g (0.28 to 0.34 oz). It is a smallish bird with a somewhat longer tail than other members of its genus. Adult males have a black and white streaked face and neck. Their crown, back, and rump are black with white or pale gray streaks. Their tail is black with white edges and tips to the feathers. Their wings are black with wide white edges on the coverts and narrower white edges on the flight feathers. Their throat, breast, and belly are white with light black streaks on the breast and flanks. Voice: One description of the stripe-chested antwren's song is "a fast repetition of a musical phrase, 'chidu-chidu-chidu-chidu...' with up to 12 or so notes". Its call is "a doubled note followed by a short descending trill, 'chiwi-chrrrrrrt' ".
