Chucao Tapaculo
Scelorchilus rubecula
Fairly common to common in native temperate forest, adjacent shrubbery, wooded patches, and thickets along rivers and streams, especially with bamboo. Loud ringing song is commonly heard, but calling birds can be elusive. At other times can be confiding, walking out at close range as if curious, usually with tail cocked. Plumage distinctive, with bright rusty eyebrow, throat, and breast. Compare with the larger and fatter Chestnut-throated Huet-huet.
识别特征
The chucao tapaculo is 18.5 to 19 cm (7.3 to 7.5 in) long. Three specimens of unknown sex weighed 42.6 to 45.4 g (1.50 to 1.60 oz) and a single male specimen weighed 53.7 g (1.89 oz). The adult is dusky brown above; much of the face and the throat and upper breast are rufous. The rest of the breast is dark gray with white bars and the flanks and vent are reddish brown to olive brown.
分类信息
The chucao tapaculo has two subspecies. The nominate Scelorchilus rubecula rubecula is primarily found in central Chile from the Biobío Region south to the Aysén Region and the adjoining parts of Argentina. It has occasionally been recorded further north and once in the far southern Magallanes Province. The other subspecies, S. r. mochae, is found only on Mocha Island off the Chilean coast.

行为
The chucao tapaculo's diet is dominated by arthropods and seeds. It forages on the ground alone or in pairs. It usually remains hidden in dense foliage but occasionally feeds in more open areas.<p>In Chile the chucao tapaculo lays eggs in September to October and in Argentina, November. The open cup nest is made of soft grass and rootlets built at the end of a burrow up to 3 m (9.8 ft) deep. Two to three eggs are laid. Both the male and female tend nestlings. This species showed a pattern of aggressiveness and territoriality towards the other species of tapaculos in the forest of southern Chile.<p>The chucao tapaculo has a loud song beginning and ending with soft churrs surrounding four or five clearer, louder, and higher pitched notes [1].

Celestial Monarch
Hypothymis coelestis
A fairly small, rather long-tailed bird of lowland forest. Has turquoise wings and tail, an indigo chest and neck, a pale blue crown and crest, and a white belly. The male is brighter blue and has a longer crest than the female. Similar to Black-naped Monarch, but has a crest. Also similar to Short-crested Monarch, but is paler blue with a longer crest. Song is a short series of clear piping notes, ”pii-pii-pii.”
Sunda Forktail
Enicurus velatus
Elegant mountain stream specialist, endemic to Java and Sumatra. Typically encountered foraging alongside narrow and fast-moving forest waterways at 600-2000 meters. Dark gray above and white below, with a dark throat and slender white stripe around the forehead. Males have a gray crown, while females have a dark maroon one (difficult to see in poor lighting). Also note bright white rump. White-crowned Forktail is significantly larger, with white wingbars and a larger white forehead patch. Calls loudly, especially when alarmed, giving high thin whistles. Often bobs tail.
Gray-browed Wren
Pheugopedius schulenbergi
Bamboo-loving wren found locally on the eastern slope of the Andes in northern Peru. Brown and gray overall with black and white face and mustache stripes. Gray underparts are unspotted; crown brown with black edges. Pairs or small groups skulk in dense bamboo, where they are most often found by their remarkable voice, a truly operatic performance of low-pitched hooting whistles given by two or three birds at once.
