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".

Ocellated Antbird
Phaenostictus mcleannani
The ocellated antbird is a largish antbird with a long bill and tail. It is 17.5 to 20 cm (6.9 to 7.9 in) long and weighs about 50 g (1.8 oz). Females tend to be slightly smaller than males and weigh slightly less. The species conforms with Bergmann's rule, with birds closer to the Equator having smaller wings and bills than those further away. Except for their slight size differences, the sexes are otherwise the same, and the subspecies have very little variation. Adults have a brown-gray crown, a rufous-brown nape, bright blue bare skin around the eye, and black cheeks and throat. Voice: The ocellated antbird's primary song is a loud "high, thin series of whistles that rises then falls, with latter notes gaining in harsh quality" that has been written as "peee-peee-pee-peepee-ee-ee-ee-ee-ee-ee-ee-eer-eer". It also has a fainter version of the song with more notes but without the harsh ending and another version with "chirring" notes interspersed.
