Berlepsch's Tinamou
Crypturellus berlepschi
A very dark, chicken-like bird found in lowland rainforest in northwestern Ecuador and western Colombia. Plumage is dark gray, but can appear almost black in the shady rainforest understory. Legs, eye, and base of bill are reddish. No other tinamou in range has uniformly dark plumage. Shy and hard to see as it walks quietly on the ground inside the rainforest. Heard far more often than seen; its song is a short, high-pitched, descending whistle repeated every 10-15 seconds.
识别特征
Berlepsch's tinamou is a medium-sized bird, about 29.6–32 centimetres (11.7–12.6 in), with the male weighing 430–537 grams (15.2–18.9 oz) and the female weighing 512–615 grams (18.1–21.7 oz). The plumage of this bird varies somewhat; however there are some features that can be quantified, such as, in general the color is a brownish black to a deep sooty brown. Also, the head and throat tend to be darker than the rest of the body, with a reddish tinge to its crown and nape. The legs and feet are pink and the bill has a dark upper mandible and a pinkish lower mandible. Its bill is longer and heavier than that of the cinereous tinamou. Finally, its iris is red.<p>The juvenile form of the bird is similar in coloring to the adult; however it does have barring on its under-parts and also on its wings with a cinnamon tinge to them.
分类信息
The Berlepsch's tinamou is a monotypic species. All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds. Until the mid 20th century, this species was considered a sub-species of the cinereous tinamou, but due to its bill size, its ratio of toe and tarsus length and the fact that its plumage has conspicuous differences from that of the cinereous tinamou created enough of a question for the new species to be named.

分布与栖息地
Its range is extreme northern coastal Ecuador north into coastal Colombia, as far north as Utria National Park (Bahia de Capica). This tinamou lives in lowland moist forest in sub-tropical to tropical regions, and will also choose to live in a mature secondary forest. It has also proven that it can survive in forests that have been logged. In Colombia it will choose the coastal lowlands and hills up to 500 metres (1,600 ft), although it has been found as high as 900 metres (3,000 ft).<p>The only 2 documented sightings are at Playa de oro reserva de los tigrillos, which is in Ecuador about 20 kilometres (12 mi) north of Cotacachi Cayapas Ecological Reserve and at Milipe Bird Sanctuary about 15 kilometres (9.3 mi) west of Maquipucuna, also in Ecuador.

Versicolored Barbet
Eubucco versicolor
Brightly colored barbet of montane forest. Males are green with a yellow breast, a red belly band, and a red head; the color of the whisker can be blue or yellow depending on the subspecies. Females have a blue face and a greener body. Both sexes have a pale greenish-yellow bill. Often found singly or in pairs with mixed-species flocks, foraging in the mid-story and canopy of humid forest. Listen for a musical purr with a punctuated introductory note: “PA-prrrrr.”
South Georgia Pipit
Anthus antarcticus
This small streaky buff-brown ground-dweller is the only resident songbird on South Georgia Island, where it inhabits rocky shorelines, offshore islets, inland pools, and stands of tussac grass. Forages actively for invertebrates, running about and flicking its tail. Like many other Antarctic and subantarctic species, can be quite confiding, often allowing for close approach. Gives husky metallic “wick” and “tsik” notes, the latter typically given when in flight. Males perform a songflight display, giving jangling metallic phrases at well-spaced intervals.
Great Spinetail
Synallaxis hypochondriaca
Handsome spinetail with a highly restricted range, known only from arid Andean valleys southeast of the city of Cajamarca in northern Peru. It has a white throat and eyebrow, a streaky breast, and chestnut wings and tail. Plumage is similar to Necklaced Spinetail, but Great is much larger, and the two species do not overlap. Inhabits thorny scrub and cacti. Vocalizations include fast rattles and shrill, doubled chirps.
