Collared Antshrike
Thamnophilus bernardi
The collared antshrike is 16.5 to 18 cm (6.5 to 7.1 in) long and weighs 30 to 38 g (1.1 to 1.3 oz). Members of genus Thamnophilus are largish members of the antbird family; all have stout bills with a hook like those of true shrikes. Both sexes of this species have a bushy crest. Adult males of the nominate subspecies have a black crown and crest; their forehead has white spots. Their lores are grayish white on an otherwise black face. They have a white collar that connects to the white underparts. Their upperparts are mostly dull rufous brown with a hidden white patch between the scapulars. Voice: The two subspecies of the collared antshrike have different songs. That of the nominate is "a slow, accelerating, monotone series of deep barking notes: WUR-wur-wur-wur-wur-wur-WURL!". That of T. b. shumbae is "much faster with distinct introductory and terminal notes: WURKtr'r'r'r'r'r'r'r'r'r'r'r'r'rWURK!".

Lined Antshrike
Thamnophilus tenuepunctatus
The lined antshrike is 15 to 16 cm (5.9 to 6.3 in) long and weighs 22 to 23 g (0.78 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 are almost entirely plumaged with narrow white and wider black bars. Their crown and crest are black and their throat is streaked black and white. Adult females have a rufous crown, crest, upperparts, wings, and tail. Voice: The lined antshrike's song is "an accelerating series of abrupt nasal notes that rises in pitch initially, falls towards end, and terminates in strong, downslurred raspy note". It has been written as "hah-ha-ha-hahahahahahahaha-hánh".
