Black Bushbird
Neoctantes niger
Distinctive, chunky antbird with an upturned bill. Males are entirely black with a silvery-black bill; females are similar, but have a bright red-orange belly. Found in dense forest undergrowth, including in heliconia thickets, waterside vegetation, viny edge forest, and dense forest on nutrient poor soils. Forages singly or in pairs, and does not usually join mixed-species flocks. Its song is an easily-imitated, even-paced series of low whistles, given at a pace of about one note per second.
Identification
The black bushbird is 15 to 16 cm (5.9 to 6.3 in) long and weighs 29 to 32 g (1.0 to 1.1 oz). It is rather stocky with a short tail and an unusual upturned bill. The sexes have different plumage. Adult males are entirely black except for a small, mostly hidden, patch of white between the shoulders. Adult females are mostly sooty black with a rufous breast and upper belly.
Taxonomy
The black bushbird was described by the Austrian ornithologist August von Pelzeln in 1859 and given the binomial name Xenops niger. The current genus Neoctantes was erected by the English zoologist Philip Sclater in 1869.<p>The black bushbird is the only member of genus Neoctantes and has no subspecies.

Range and habitat
The black bushbird has a disjunct distribution. The largest range encompases south-central and southeastern Colombia, eastern Ecuador, northeastern and southeastern Peru, and western Brazil. Isolated ranges are scattered throughout central Amazonian Brazil. The species inhabits lowland terra firme and várzea evergreen forest; it is more common in the latter. It favors dense undergrowth along edges, in treefalls, and along swampy streams.

Behavior
The black bushbird is a year-round resident throughout its range.<p>The black bushbird is thought to feed on insects and other arthropods. It forages singly or in pairs in dense vegetation from the ground up to about 10 m (35 ft) above it. It occasionally joins mixed-species feeding flocks that pass through its territory but does not travel with them. It forages mostly by picking, hammering, and digging into branches, woody vines, and rotten wood. It uses its unusual bill to wedge or flake off bark or pieces of the substrate.<p>Only one nest of the black bushbird has been studied. It was found in September in Peru, a messy, bulky cup of leaves and other plant material suspended in a shrub's branch fork. The male was incubating the single egg. The nest failed the next day due to predation or a storm so the incubation period, time to fledging, and other details of parental care could not be determined. Nothing else is known about the species' breeding biology.<p>The black bushbird is not highly vocal. Its song is an "often slightly rising series of semimusical 'werk' notes" given for a minute or more at about one note per second. Its call is "distinctive, squealing, two-parted but continuous, with second part lower-pitched", a "nasal 'kyoo' ".

Stripe-backed Bittern
Botaurus involucris
Very small, striped buffy heron of wetlands and lake edges with dense reeds and rushes. Boldly striped back pattern is distinctive. In flight shows contrasting broad rusty trailing edge to wings. Usually seen as single birds hidden in reeds or making short flights low over reeds or across patches of open water. Clambers easily and stealthily; hunts from perches over water, where sits patiently before stabbing at fish. Mostly silent.
Red-throated Crag-Martin
Ptyonoprogne rufigula
A subtly colored member of the swallow family. Dark brown on the back with paler underparts. The forked tail has white spots, though these are not always easy to see. The “red throat” amounts to a slight pinkish tinge. Nests in canyons, escarpments, gorges, and on human structures. Often seen in pairs or small groups. At a distance, can be confused with “Riparia” martins; look for Pale Crag-Martin’s white tail patches. Separation from Southern Crag-Martin may be tricky, but there is little overlap in range.
Masked Saltator
Saltator cinctus
Rare and beautiful bird of high Andean cloud forest, at least in some places found especially in bamboo. Very distinctive with black breast band, face, and throat, mostly red bill, yellow eye, and white tail tips. Sexes look alike. Generally found alone or in pairs at lower to middle levels in the forest, and may occasionally join mixed-species flocks. Song is a soft, repeated “chu-chu-chu-chu-whit?”; also gives sharp, metallic squeaks.
