Kicau Nusantara The Barred Antshrike, Thamnophilus doliatus, is a passerine bird in the antbird family. It is found in the Neotropics from Tamaulipas, Mexico, through Central America, Trinidad and Tobago, and a large part of South America east of the Andes as far south as northern Argentina, Bolivia and Paraguay. There is one accepted record from southern Texas. It is found in a wide range of wooded habitats (even gardens and parks) in both humid and arid regions. Throughout a large part of its range, it is among the most common antbirds. The Barred Antshrike is typically 16.5 cm long, and weighs 25 g. The male is barred all over with black and white, and has a white-based black crest that is raised in display. The female is rufous above with a chestnut crest. The sides of her head and neck are streaked with black, and the underparts are rich buff.
The subspecies vary primarily in the overall darkness and the amount of barring and hue of the underparts. For example, in the Tobagoian race T. d. tobagensis males are whiter below, and females darker, than in the nominate subspecies. The most distinctive subspecies is capistratus of the Caatinga in north-eastern Brazil, where males have uniform black crown (no white barring to the base) and females have streaked throat and faintly barred belly. It is also the only subspecies where the iris is deep maroon-red (not yellow). It has recently been suggested that it should be considered a separate species, the Caatinga Barred Antshrike. wikipedia
