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.

分布与栖息地
The Yungas guan is found on the east side of the Andes in the Southern Andean Yungas of southwestern Bolivia and northwestern Argentina. It inhabits subtropical evergreen forest from below 1,000 m (3,300 ft) up to approximately 1,900 m (6,200 ft).
行为
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.

Spectacled Bristle-Tyrant
Pogonotriccus orbitalis
Small tyrannulet with weak yellow wingbars. Olive yellow, with a grayish head, thin whitish yellow eyering, and dark eye. Weakly marked overall; its orange lower mandible is a good field mark. Found in the midstory and canopy of montane forest in a fairly narrow band in the foothills of the Andes, roughly 500-1400 m in elevation. Sometimes joins mixed-species flocks. Listen for its thin, sputtering trill that rises slightly; buzzier and softer than other bristle-tyrants.
Emerald-chinned Hummingbird
Abeillia abeillei
Very small, short-billed hummingbird of humid evergreen and pine-evergreen forest in highlands and upper foothills; uncommon. Usually feeds low, often at banks of flowers along edges and roadsides. Feeding flight is usually quick and hard to follow. Best identified by small size, big white spot behind eye, and rather liquid twittering call (similar to Stripe-tailed Hummingbird, which occurs in the same areas but looks quite different).
Red-cheeked Parrot
Geoffroyus geoffroyi
Compact, bulky medium-sized green parrot of wet forests in Cape York and lowlands of New Guinea. Male has rose-pink face, violet crown, reddish upper mandible, and pale eye. Female has brown head, pale eye, and dusky bill; juvenile greenish overall with dark eye and orange bill that turns gray. In flight, bright pale blue underwings contrast with green belly and pink face in male. Much larger than tiny Double-eyed Fig-Parrot. Calls include high-pitched squeaks (similar to Australian King-Parrot) and repeated incisive squeaks.
