Cinnamon-throated Woodcreeper
Dendrexetastes rufigula
Large plain brown woodcreeper of Amazonian lowlands. Reddish brown overall with olive brown underparts, a heavy gray bill, and fine white breast streaking on some individuals. Typically found in young forest and forest edge, often around rivers and lakes. Most other woodcreepers have much more prominent streaking. Compared to similar Plain-brown and White-chinned Woodcreepers, this species has a more even brown face without noticeable facial markings and a heavier, lighter gray bill. Listen for its song, an explosive, decelerating rattle punctuated with a low churr at the end.
识别特征
The cinnamon-throated woodcreeper is one of the larger woodcreepers, with a heavy body, short wings, and a short, stout, bill with a slightly hooked tip. It is 22.5 to 27 cm (8.9 to 11 in) long. Males weigh 64 to 74 g (2.3 to 2.6 oz) and females 66 to 77 g (2.3 to 2.7 oz). The sexes are alike. The nominate subspecies D. r. rufigula has mostly medium brown upperparts with a paler crown and rufous-chestnut wings, rump, and tail. A few whitish streaks span the nape and upper back. It is generally paler and more cinnamon-brown below. Its throat is a brightish rusty buff, its breast has wide black-edged whitish streaks that extend to the sides of the neck, and sometimes weak darker bars on the lower belly and undertail coverts. Its iris is red to light brown, its bill horn-gray, bluish horn, or brownish to dull greenish yellow, and its legs and feet slate gray, greenish gray, bluish black, or brown.<p>Subspecies D. r. devillei has a weaker pattern than the nominate, with much fainter streaks on the breast, none on the neck, and no bars on the belly. D. r. paraensis is very like the nominate, but with a bold white supercilium and rounder streaks on the breast and neck. D. r. moniliger is duller and less rufescent than the other subspecies, but has bolder streaking on the breast and neck.

分布与栖息地
The subspecies of the cinnamon-throated woodcreeper are found thus:<p>The cinnamon-throated woodcreeper mostly inhabits humid forest, both terra firme and várzea. In the Guianas it typically occurs in forest on sand ridges and savanna. It favors palm forest, the edges of evergreen forest, and mid- to late-age secondary forest rather than the interior of primary forest; it also frequently occurs on river islands. In elevation it mostly occurs below 500 m (1,600 ft) but is occasionally found as high as 950 m (3,100 ft) in the Andean foothills at the western edge of its range.

Olive-shouldered Parrot
Aprosmictus jonquillaceus
A large, long-tailed green parrot with an orange bill and a wing patch, red in males and yellow in females, that is visible both perched and in flight. Juvenile is like female, but lacks wing patch. Singles or small flocks can be found in a variety of wooded areas, like forests and plantations, in lowlands and mountains. Limited to a few islands in the Lesser Sundas. Distinguished from Olive-headed and Marigold Lorikeets by its larger size, its broad square tail, and its lack of a dark hood. Gives raucous, shrill screeches, high-pitched tinkling, and lower-pitched “kraak-kraaak” calls.
Banded Woodpecker
Chrysophlegma miniaceum
Small but brightly-colored woodpecker with a spiky crest. Slight variation across its range, but all birds have a dark orangish face, dark chestnut wings, black-and-white-striped underparts, and a dark tail. Female duller overall, with a plainer face. Inhabits lowland and foothill forests, edges, and gardens, where it can be reasonably common. Often seen singly, but can be encountered in closely-foraging pairs. Favors tall thick trunks. Gives sharp “kek” or “week” call notes. Difficult to confuse with any other small woodpecker.
Giant Coot
Fulica gigantea
Distinctive huge coot of lakes and bogs in high Andes. Often seen standing along shorelines or on big weed-matted nest mounds. Note the colorful bill, long red legs, and huge feet. Prolonged nesting season means that all stages of nesting and young can be seen together, from small fuzzy black chicks to full-sized juveniles, which are pale grayish with a frosty whitish head and neck. Often rather aggressive. Loud clucking and purring songs carry well and are given frequently.
