Dull-mantled Antbird
Sipia laemosticta
The dull-mantled antbird is 12.5 to 15.0 cm (4.9 to 5.9 in) long and weighs about 25 g (0.88 oz). Adult males have a blackish gray to slate-black head, neck, and upper mantle. The rest of their upperparts are dark reddish brown, chestnut, or olive with a usually hidden white patch between their scapulars. Their flight feathers and tail are blackish brown with dark reddish brown edges. Their greater wing coverts are dark reddish brown with cinnamon or rufous tips; their median and lesser coverts are black with white tips. Voice: The male dull-mantled antbird's loudsong is "a countable series (e.g., eight notes, over 1.8 seconds) of short notes that begins with three upslurred to flat notes and abruptly switches to five evenly paced downslurred notes, e.g., tsee tsee tsee, tyew-tyew-tyew-tyew".

Giant Antshrike
Batara cinerea
The giant antshrike is the largest antbird, 27 to 35 cm (11 to 14 in) long and weighing 100 to 155 g (3.5 to 5.5 oz). The species exhibits significant sexual dimorphism, though both sexes have a crest, a very long and wide tail, and a long gray bill with a hook at the end like true shrikes. Adult males of the nominate subspecies have a black forehead, crown, and crest. Their back, wings, and tail are barred with black and white. Their face, nape, throat, and underparts are neutral gray. Adult females have a rufous crest with some black feather tips. Voice: The giant antshrike's song is a "series that starts with a short trill and continues with a fast series of notes that increase in strength and pitch, leveling out and decelerating at the end". Its calls include a "long, raspy, downward-inflected snarl, often repeated rapidly, and a short even series of abrupt loud notes".
