分类信息
Sick's swift was formally described in 1907 by the Austrian ornithologist Carl Eduard Hellmayr from specimens collected in the Santiago del Estero Province of northern Argentina. Hellmayr considered it to be a subspecies of the ashy-tailed swift and coined the trinomial name Chaetura andrei meridionalis. The specific epithet is a Latin word meaning "southern". Based on a study by the ornithologist Manuel Marín, Sick's swift is now considered to be separate from the ashy-tailed swift and has been elevated to species status. The English name commemorates the German-born ornithologist, Helmut Sick, who studied Brazilian birdlife.

分布与栖息地
It breeds in south-eastern Brazil and adjacent parts of Argentina, Paraguay and Bolivia, but is believed to spend the Austral winter further north in the Amazon basin, northern South America and Panama. Its exact wintering range is, however, poorly known due to the highly complex matter of field identification of a number of very similar Chaetura swifts found in central and northern South America. In addition to the previously mentioned countries, there are records from Colombia, Venezuela, Suriname and French Guiana.<p>It is generally common, but confirmed records outside its breeding range (where it is the only large Chaetura swift, and therefore relatively easy to identify) are infrequent. Its preferred habitat is lowland evergreen forest edge, secondary forest, open woodland and second-growth scrub but it can be seen flying over virtually any habitat during its annual migration.

Northern Bentbill
Oncostoma cinereigulare
Tiny flycatcher of humid forest and woodland in tropical lowlands. Inconspicuous, mainly foraging at low to mid-levels in forest interior and edge, where flits from perch to perch and then sits still. Heard far more often than seen: common call a low, frog-like churr. Overall plumage color and pattern much like many flycatchers, but note its tiny size, ‘broken-nose’ bill profile, pale eyes, and relatively long, thin, pale pinkish legs.
Black-eared Miner
Manorina melanotis
Rare, medium-sized honeyeater found only in a few areas with dense intact mallee woodland (such as Gluepot Reserve). Grayish brown above, paler gray below, with pale gray crown, yellow bill, yellow eye patch, and a dark cheek patch. Hybridizes with Yellow-throated Miner, which makes identification difficult, as hybrids show a mix of the features of both species. In Black-eared, the moustache is darker than the throat (moustache is paler in Yellow-throated) and the cheek patch entirely black (patch has silver flecks in Yellow-throated). In flight, note the rump is the same color as the back and tail (rump is paler in Yellow-throated). Aggressive and territorial; lives in colonies and vigorously defends the territory area against pretty much anything that moves.
Saturnine Antshrike
Thamnomanes saturninus
Fairly small antshrike. Males are dark gray with a black throat. Females are tinged brown above and tawny below with a contrasting whitish throat. Found in the understory of lowland humid forest. Often leads mixed-species flocks; occasionally attends army-ant swarms. Sings a series of gradually ascending notes that ends with a harsh final note. Similar to Cinereous Antshrike, which can occur in the same flocks, but differs in throat color and in song.
