Thamnophilus multistriatus

Small28 gWoodland

The bar-crested antshrike is 15 to 16.5 cm (5.9 to 6.5 in) long and weighs 21 to 23 g (0.74 to 0.81 oz). Members of genus Thamnophilus are largish members of the antbird family; all have stout bills with a hook like those of true shrikes. This species exhibits marked sexual dimorphism though both sexes have a crest. Adult males of the nominate subspecies T. m. multistriatus are almost entirely plumaged with alternating black and white bars, including their crest. The exception is their face and throat, which are streaked black and white. Voice: The bar-crested antshrike's song is "much like Barred Antshrike but lazier with marked acceleration at end; typically 6-10 notes, dū, dü dü dü du du-du-da'da".
