Ancistrops strigilatus
The chestnut-winged hookbill is 17 to 19 cm (6.7 to 7.5 in) long and weighs 30 to 39 g (1.1 to 1.4 oz). It is a largish furnariid with distinctive plumage, and a moderately hooked bill resembling those of Thamnophilus antshrikes. The sexes have the same plumage. Adults have a wide whitish to buff supercilium, grizzled brownish and buff lores, brown ear coverts with pale streaks, and yellowish buff malars. Their crown is very dark brown with obvious narrow gold-buff streaks. Their back is a paler, somewhat grayish olive, brown, with paler and less well defined streaks. Voice: The chestnut-winged hookbill's song is "a fast, ascending trill that increases in loudness as it levels off in pitch, then ends abruptly" and can last for 30 seconds or more. It has also been described as a "sustained gently undulating, slightly angry-sounding rattle". Its calls include "a harsh, buzzing 'bzzt' " and "teejuw". It also makes a short ascending trill.

Sclerurus obscurior
The dusky leaftosser is 15 to 17 cm (5.9 to 6.7 in) long and weighs 20 to 30 g (0.71 to 1.1 oz). The sexes are alike. Adults of the nominate subspecies S. o. obscurior have dark reddish to chestnut brown upperparts, with their rump and uppertail coverts being more chestnut than the reddish back. Their wings are darker brown than their back and their tail is dark brown to black brown. Their face is brownish, their throat is tawny chestnut, and their chest and breast are a darker chestnut. Their bill is fairly long and straight with a dark maxilla and a bicolored mandible. Voice: The song of the dusky leaftosser varies somewhat in pitch and number of notes among the subspecies, but is generally "a melodious descending series of 4‒15 upslurred whistles". It may start with "a sharp spik! note" and end with a "few stuttering short notes". Its principal call is a "short sharp explosive single note Tseek!".
