Ochre-flanked Tapaculo
Eugralla paradoxa
Heard but rarely seen; a retiring little gray bird of bamboo thickets and other dense shrubbery at forest edges, along streams, and in wooded patches. Can be confiding if an observer is quiet. Feeds by hopping quickly on the ground and through bamboo. Plumage is leaden blue-gray overall with faint paler spectacles, rich buffy flanks, and pale legs. Slightly larger and stouter-billed than Magellanic Tapaculo, which often occurs alongside Ochre-flanked in bamboo thickets (bill of Magellanic is slender).

分布与栖息地
The ochre-flanked tapaculo is a year round resident of south-central Chile (Maule Region to Los Lagos Region) and the western parts of the adjoining Argentinian provinces of Neuquén, Río Negro, and Chubut. It is found from sea level to 900 m (3,000 ft) and perhaps higher, where it inhabits dense undergrowth and bamboo in Nothofagus and mature secondary forest.

行为
The ochre-flanked tapaculo forages in pairs on and near the ground in dense cover. Its primary prey is thought to be arthropods.<p>The ochre-flanked tapaculo is known to "double brood", laying eggs in September and again in November. The nest is a large ball of straw and grass with a side entrance that is usually placed 1 to 2 m (3.3 to 6.6 ft) above ground, though sometimes as high as 7 m (23 ft). Nests have been found in thick bushes, small trees, and piles of branches.<p>The ochre-flanked tapaculo's song is a short series of sharp "check" notes [1]. The members of a pair keep in contact with a softer "kek" call [2].

Red-fronted Lorikeet
Hypocharmosyna rubronotata
A small, long-tailed lorikeet. Green body with black upper tail, red rump and a red bill. The male has a red forehead, violet-blue cheek and a red patch in front of the shoulder whereas the female has some yellow-streaking behind the eye. Very similar to Red-flanked Lorikeet, but male Red-fronted has a red patch on the forehead rather than chin and has less pronounced yellow wing bar in flight. Voice, a series of sharp, high-pitch, arhythmic “tsik!” notes.
Diabolical Nightjar
Eurostopodus diabolicus
A dark, cryptically patterned nightjar with a bold buff collar, and prominent pale gray patches on the upperparts. In flight, note the small white mark on the outer wing. Inhabits forest and edges in the foothills and mountains. Pairs often roost on the ground. Restricted to Sulawesi. Never shows white in the tail, unlike Sulawesi and Savanna Nightjars. Smaller than Great Eared-Nightjar, and never hawks above the canopy. Song is a rapid series, “ke-ke-ke-ke-ke-ke.” Also gives soft “whip” calls.
Gray Fantail
Rhipidura albiscapa
Small songbird with long, pale-tipped tail, tiny, thin bill. Gray above, pale below, with narrow pale wingbars and a thin black border between white throat and chest. Frequently cocks and fans tail. Subspecies vary in upperparts tone and extent of white in the tail. Inhabits wide range of habitats, very active in foraging, and rarely perches in the same place for long.
