Yungas Guan
Penelope bridgesi
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.
识别特征
Male and female Yungas guans are alike. They are chestnut above and dull reddish brown below. The belly has brown to orange horizontal markings and the tail is dark brown. The head and back of the neck are black. Feathers of the neck, back, and chest have white edges that are significantly larger than those of P. obscura. The bare skin of the face is slate gray and the wattle is red. <p>The Yungas guan is larger than P. obscura; the lengths of nine specimens were between 77.0 cm (30.3 in) and 89.0 cm (35.0 in) compared to 48.0 cm (18.9 in) and 66.0 cm (26.0 in) for two specimens of P. obscura.
分类信息
Prior to late 2020, the Yungas guan was considered a subspecies of dusky-legged guan (Penelope obscura). A 2018 publication detailed many morphological differences between them. An earlier publication had highlighted their very different vocalizations. Based on that evidence and the members' personal knowledge, the South American Classification Committee of the American Ornithological Society elevated it to species rank in December 2020, and the International Ornithological Congress followed suit in January 2021.

The Yungas guan eats fruit and leaves with the proportions and species of each varying throughout its range. Though the bird is generally sedentary, it is thought to change its elevation in different seasons. The species' breeding season is mainly between October and December.

Black-capped Tinamou
Crypturellus atrocapillus
Subtly colorful tinamou of dense habitats in the lowlands and Andean foothills. Almost exclusively found in bamboo thickets, but also occasionally found in dense riverside vegetation and secondary growth, including around agriculture. Rarely seen, but frequently heard throughout the day; it usually gives about one call note per minute, a springy “bwow”. The most helpful visual field mark is its bright orange legs; it also has a black or dark gray cap, and brown plumage with cold gray head and neck, and reddish orange throat.
