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].

Gray-headed Tody-Flycatcher
Todirostrum poliocephalum
Tiny brightly-colored flycatcher with a fairly long pointed bill and an ample slender tail. Note the largely black head apart from a large yellow spot in front of the pale eye. Olive above and bright yellow below; the black wings are yellow edged . Similar to Common Tody-Flycatcher, but with yellow spots on the face. Found at the edge of forests, second growth, and in gardens and urban parks. The song is a sharp “tchip-tchip-tchip.”
White-throated Tinamou
Tinamus guttatus
Secretive chickenlike bird that walks on the ground inside forest. Very plump; looks tailless. A large tinamou but smaller than similar Great. If seen well, look for distinctive pale spotting on wings along with white throat and lower belly. Fairly common and widespread in lowland Amazonian forest, occasionally up into the foothills. Far more often heard than seen: listen for its haunting song, a pair of low hoots, the second note rising.
Unstreaked Tit-Tyrant
Uromyias agraphia
Small gray flycatcher with a simple, bold facial pattern. Has a brownish gray body with a black eyeline and crown and a white eyebrow; usually has very faint streaking through the face and breast. Looks big-headed and usually perches upright.

Listen for its lisping high song and stuttered “peep” call notes.
