Chestnut-collared Swallow

Large guan with a long tail and red throat wattle. Dark brown overall with extensive white markings on wings. Unlike most other members of its genus, Yungas has dull grayish legs. Found in montane forests and edges. Listen for loud, harsh calls often given in a series. Restricted range in northwestern Argentina and southern Bolivia. Usually in pairs or small groups; often seen feeding at fruiting trees, but can be seen walking on the ground.

Small and fairly bright antpitta found in foothills and subtropics from Costa Rica to Bolivia. Typical antpitta shape: plump and short-tailed. Dull brown above. Messy-looking buffy face and eyering. Some geographic variation: breast color varies from buffy to whitish, and some populations show bold dark scaling on breast, while others are nearly unmarked. Sexes similar. Shy and difficult to see; stays on or near the ground in forest, often perching on small limbs a couple meters high (more so than the larger antpittas). Swings its body side to side. Song can be difficult to detect: a simple, extremely high pitched, descending whistle. Occurs from around 500–2,500 m, usually lower than other small antpittas.

Huge cuckoo that is black above and white below. Immature has white barring across its upperparts. Looks raptor-like in powerful, swooping flight. Uncommon bird of rainforest, gallery forest, and moist woodland, especially miombo. Call is a loud, repeated “wheet-it”, often given in a high display flight. Adult is separated from Great Spotted, Levaillant’s, and Pied cuckoos by its lack of a crest or white in the wing. Immature is similar to Great Spotted Cuckoo, but has black-and-white speckles on the head, and lacks a crest.
