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.
识别特征
The saturnine antshrike is 13.5 to 14.5 cm (5.3 to 5.7 in) long and weighs 19 to 21 g (0.67 to 0.74 oz). Adult males of the nominate subspecies have darkish gray upperparts with a white patch between their scapulars. Their wings are darkish gray with white edges to feathers at the bend and white tips on the coverts. Their tail is darkish gray with small white tips on the feathers. Their throat and upper breast are black and the rest of their underparts darkish gray with usually some white edges on the belly feathers. Adult females have olive-brown upperparts with a rufescent tinge. Their wings and tail are rufous. Their throat is white, their breast olive, and the rest of their underparts deep tawny-buff. Males of subspecies T. s. huallagae have less black on their throat than the nominate; females have gray spots on their throat and a darker breast than the nominate.>
分类信息
The saturnine antshrike was described by the Austrian ornithologist August von Pelzeln in 1868 and given the binomial name Thamnophilus saturninus. During the twentieth century several authors placed it in genus Dysithamnus and treated it and what is now the dusky-throated antshrike (T. ardesiacus) as conspecific. The two now are considered a superspecies.<p>The saturnine antshrike has two subspecies, the nominate T. s. saturninus (Pelzeln, 1868) and T. s. huallagae (Cory, 1916).

分布与栖息地
Subspecies T. s. huallagae of the saturnine antshrike is the more western of the two. It is found south of the Amazon and Marañón rivers in northeastern Peru and into southwestern Amazonian Brazil's Acre state. The nominate subspecies is found in south-central Amazonian Brazil south of the Amazon from Acre east to the Tapajós and Teles Pires rivers and south to Rondônia and northern Mato Grosso, and into extreme northeastern Bolivia. The species primarily inhabits the understorey of terra firme evergreen forest and occurs less often in várzea forest. In elevation it occurs mostly below 300 m (1,000 ft) but reaches 650 m (2,100 ft) in Bolivia.

Pink-footed Puffback
Dryoscopus angolensis
Small bushshrike in which males and females are very different. Males are mostly black and gray, with white on the throat. Females are brown on the back, gray on the head, and buff below. Found in mountain and hill forest. Sometimes joins mixed-species flocks. The most common vocalization is a rising “cheeeu,” but also gives scolding and ratcheting calls. Somewhat similar to Sabine’s Puffback, but males separated by the gray rump and underparts, and females separated by their smaller size and less rufous coloration.
Hutton's Vireo
Vireo huttoni
Drab olive overall with white eyering, bold wingbars, and thick bill. Found in forested areas with a mix of oak and conifers, usually foraging in the middle levels. Often in mixed flocks with other small songbirds. Resident along the Pacific coast from British Columbia to northern Baja and in interior mountains from Arizona and Texas to Guatemala. Remarkably similar to Ruby-crowned Kinglet, but thicker-billed and more sluggish; also note bluish legs. Also compare with Dwarf Vireo in Mexico. Listen for distinctive repetitive song of clear or buzzy notes.
Pine Flycatcher
Empidonax affinis
Small flycatcher of pine-oak forest and edge in highlands; often in clearings and orchards with small deciduous trees (often not in pines). Other Empidonax flycatchers occur alongside Pine Flycatcher, especially very similar Dusky and Hammond’s Flycatchers, which are winter migrants. On Pine, note the bright pale teardrop-shaped eyering similar to Hammond’s and an entirely pale orangish underside to the bill (like Cordilleran Flycatcher, which is greener and has a broader bill ). Call is a rather quiet “pwip,” somewhat similar to Dusky but very distinct from Hammond’s.
