Spot-backed Antshrike
Hypoedaleus guttatus
The spot-backed antshrike is a large antbird, 20 to 21 cm (7.9 to 8.3 in) long. The species exhibits slight sexual dimorphism. Both sexes have a short, heavy, gray bill with a hook at the end like true shrikes. Adult males have a black crown, nape, and upperparts spotted with white and a brownish black tail with white bars. Their throat and breast are white and their sides pale gray. Their belly and crissum are nearly white in the northern part of their range and gradually darken to brownish yellow to the south. Voice: The spot-backed antshrike's song is a "very high, slow, at first rising then descending, shivering rattle" that lasts four or five seconds. Its calls include a "long, downward-inflected whistle", a "shorter, slightly descending churr", and an "abrupt 'chip' ".

Zeledon's Antbird
Hafferia zeledoni
Zeledon's antbird is 17 to 20 cm (6.7 to 7.9 in) long and weighs about 40 to 56 g (1.4 to 2.0 oz). Both sexes have a wide pale blue ring around their eye and a deep red iris. Adult males of the nominate subspecies are mostly black with variable amounts of white on the wing and wing coverts; the white is almost always hidden. Adult females are mostly dark brown that is paler on their underparts than above. Their lores and face are black. Males of subspecies H. z. berlepschi have more white on their wings than the nominate. Females are a paler and brighter brown than the nominate. Voice: The song of the male Zeledon's antbird is a "rapidly delivered...loud ringing and slightly descending series of clear whistled notes, 'peer-peer-peer-peer-peer-peer-peer-peer', slowing a bit toward end". Both sexes "give an explosive 'cheek!' call and a fast scolding 'jee-jee-jit' ".
