Buff-bellied Puffbird
Notharchus swainsoni
Uncommon chunky pied species, usually noticed perched motionless in the canopy of humid and lower montane forests. Note its sturdy bill, narrow white forehead, white breast with a narrow black collar, and buffy belly. Song is a descending series of whistles. No similar species in its range.
识别特征
The buff-bellied puffbird is about 23.5 cm (9.3 in) long and weighs 72 to 75.6 g (2.5 to 2.7 oz). The crown and upperparts are black with a green gloss and buffy edges to the feathers. It has a narrow white forehead, throat, and upper breast. The sides of the face and a thin band around the nape are grayish white. A wide black band separates the upper breast from the buffy to pale rufous belly. The flanks are gray. Its eye color can be straw, brown, or red.
分类信息
During the second half of the twentieth century, the buff-bellied puffbird and what are now the white-necked puffbird (N. hyperrhynchus) and Guianan puffbird (N. macrorhynchus) were treated as conspecific. It is now treated as its own monotypic species.

分布与栖息地
The buff-bellied puffbird is found in eastern Paraguay, far northeastern Argentina's Misiones Province, and in southeastern Brazil from southern Bahia and Espírito Santo south to Santa Catarina. It is resident in Argentina but possibly moves from other parts of its range into São Paulo state in the austral summer. It inhabits lowland humid primary and secondary forest.

行为
The buff-bellied puffbird hunts by sallies from a high bare perch to capture insects and sometimes small vertebrates; it also eats some fruits. It investigates army ant swarms.<p>The buff-bellied puffbird breeds in September and October in the southern part of its range; the season elsewhere is not known. It excavates a nest cavity in an arboreal termitarium, and all other known breeding phenology at least for the Paraguayan subspecies is limited to one research paper.<p>The buff-bellied puffbird's song is a "descending sequence of whistles, varying in rhythm, 'ui-ui---dibule-dibule...'."

Streak-throated Swallow
Petrochelidon fluvicola
A small brown-black swallow with a short tail and comparatively weak flight. The forehead, crown, and back of the neck are dull chestnut with faint dark streaks. The back is glossy deep blue with a few narrow whitish streaks; the rump is pale brown and is more prominent in flight. The wings and tail are blackish-brown, and the tail almost square-ended. Underparts are buffy white with blackish-brown streaks, especially the chin, throat, and upper breast. Juvenile is duller and browner than adult, with buff feather edges and faint streaks on underparts. Found mostly as individuals in mixed swallow flocks; different, weaker flight action is characteristic.

Lesser Honeyguide
Indicator minor
A small, inconspicuous, gray-green bird with striking white outer tail feathers that are evident in undulating flight. It is easily confused with other honeyguides, but a pale spot on the top of the bill and subtle, darker (moustachial) streaks on either side of the throat are characteristic. Often it is the commonest honeyguide in mixed woodland, cultivation, and pasture; it can be tracked down by following its continuous, strident “swiiit, swiiit, swiiit” calls. The smaller Least Honeyguide is often more heavily streaked underneath, and Pallid Honeyguide has a plainer face and indistinct moustachial streaks; both have differing vocaliations

European Red-rumped Swallow
Cecropis rufula
Brightly-colored swallow with a deeply forked tail, pale orangish rump, black squared-off undertail coverts, an incomplete orange collar, and faint streaking below. Juveniles average paler and lack extensive orangish tones; may resemble house-martins but note deeply forked tail. Typically glides on stiff, flat wings, flying quite languidly with shallow wingbeats. Builds mud nests in mountains, on sea cliffs, and on buildings and other structures. Forages over open areas. Frequently gives a short, sparrow-like “twi’wit.” Very similar to African Red-rumped Swallow, but shows much heavier streaking below.
