Para Foliage-gleaner
Automolus paraensis
Medium-sized and typically noisy foliage-gleaner with an olive-brown back, buff underparts, a white throat, and a rusty tail. Found mainly in humid lowland forest, often near streams, but also sometimes in seasonally flooded forests. Forages from the understory to middle levels. Acrobatically looks for food by gleaning dead leaves, and often accompanies mixed-species flocks.
Identification
The Para foliage-gleaner is 18 to 19 cm (7.1 to 7.5 in) long and weighs 32 to 41 g (1.1 to 1.4 oz). It is a fairly large member of its genus and has a heavy bill. The sexes have the same plumage, and differ very little from the formerly conspecific olive-backed foliage-gleaner. Adults have a mostly blackish brown face with reddish streaks on the ear coverts and grizzled blackish brown and buff lores. Their forehead is blackish brown with wide but inconspicuous rufescent brown streaks that become faint scallops on the grayish brown crown. They have a vague dark brown collar with faint light brown streaks. Their back and rump are rich dark olivaceous-brown that blends to dark reddish brown uppertail coverts. Their wing coverts are rich dark brown and their flight feathers slightly paler with a rufescent tinge. Their tail is dark rufous. Their throat and the sides of their neck are white, their center breast white with a gray wash that becomes buffy before their light buff-brownish belly. The sides of their breast are dark olive-brown, their flanks rufescent brown, and their undertail coverts pale brown. Their iris is dark brown, light brown, or hazel; their maxilla black to dark olive-horn; their mandible olive horn to gray to pale brown; and their legs and feet grayish green to yellowish olive. Juveniles are slightly darker and duller than adults.
Taxonomy
The Para foliage-gleaner was previously treated as a subspecies of the olive-backed foliage-gleaner (A. infuscatus). A 2002 publication detailed significant vocal differences between them; based on that evidence major taxonomic systems elevated it to species rank. The Para foliage-gleaner, olive-backed foliage-gleaner, Pernambuco foliage-gleaner (A. lammi), and white-eyed foliage-gleaner (A. leucophthalmus) form a superspecies.<p>The Para foliage-gleaner is monotypic.

Range and habitat
The Para foliage-gleaner is found only in Brazil south of the Amazon, from the right bank of the Rio Madeira east to the Atlantic in Maranhão state and south to Rondônia and Mato Grosso states. It inhabits tropical evergreen forest, primarily terra firme but also várzea and secondary forest. In elevation it ranges from near sea level to 700 m (2,300 ft).

Behavior
The Para foliage-gleaner is a year-round resident throughout its range.<p>The Para foliage-gleaner feeds on a variety of larval and adult insects and spiders, and also eats small lizards. It forages singly or in pairs, and most of the time as part of a mixed-species feeding flock. It feeds mostly in the forest undergrowth though it occasionally will do so to the mid-storey but only rarely to the subcanopy. It acrobatically gleans and pulls prey from epiphytes, debris, bark crevices, and especially from clumps of dead leaves.<p>The Para foliage-gleaner's breeding season has not been defined but includes at least January and February. It builds a cup nest of plant fibers in a chamber at the end of a tunnel it excavates in an earthen bank. The clutch size is two eggs. Nothing else is known about its breeding biology.<p>The Para foliage-gleaner's song is a "very high, penetrating, sharp 'kreet-kreetkrititit', slightly descending". Its call is a nasal "wheet wheet".

Yellow-eyed Babbler
Chrysomma sinense
An odd-looking babbler which looks and behaves like a prinia on steroids. Brown above and white below with rufous wingtips. Red eyering is unique. Scrambles about in reedbeds, scrub, field edges, and grassy meadows in small flocks and pairs. Scales stems like a parrotbill and hangs acrobatically like a tit or leaf warbler. Strident, melodic song has a somewhat hoarse, nasal quality. Calls include repeated descending whistles, energetic chattering, and dry chittering.
Cactus Parakeet
Eupsittula cactorum
Medium-sized parakeet with a contrasting green back, yellow-orange belly, and pale brown face. Note the white bare eyering. Found in pairs or small groups in scrubby areas (caatinga) with shrubs and cactus, but also frequents marginal agricultural land such as degraded pasture and cultivated areas with rice and maize.
Striped Flufftail
Sarothrura affinis
Small rail of grassland and heath. Very shy and elusive bird that is unlikely to be seen unless expressly looking for it. Male has a rufous head and black body with heavy white streaks. Female brown with barring and spotting below. Found in fynbos, montane heath, grassland, and locally in wetlands. Call is a series of long, rising, hollow hoots. Similar to Streaky-headed and Red-chested Flufftails, but male has less rufous on the chest, and female is paler and more patterned below. Usually found in drier habitats than other flufftails.
