Black-bodied Woodpecker
Dryocopus schulzii
Large woodpecker endemic to the deep thorn forest of the Chaco of western Paraguay, SE Bolivia, and N Argentina. Similar to Lineated Woodpecker, but note all black underparts and pale auriculars on Black-bodied. From Cream-backed Woodpecker by darker bill, black back, and long drum. Calls a rising, nasal “kwee?” note given in a long repetitive series. Drum long, quick, and accelerating, but tends to be shorter than the drum of Lineated.
Identification
The black-bodied woodpecker is 29 to 30 cm (11 to 12 in) long. Both sexes have a long pointed crest. Adult males have a red forehead and crest. They have gray ear coverts, a very thin and short white stripe behind the eye, a white stripe from the lores to under the ear coverts and continuing down the side of the neck, a red malar stripe with a bit of black at its back end, and a white chin. Adult females have a black malar stripe and a blackish lower forehead but are otherwise the same as males. Adults of both sexes have a black throat and hindneck and are mostly black below the neck. The southern population has black scapulars; those of the northern population have white on the scapulars' outer webs that continues the white neck line. Their flight feathers are black with white bases. The upper side of their tail is black with white feather shafts; the underside is black to brownish black. Their flanks and lower belly often have some faint yellowish barring. Their bill is a long pale ivory-white chisel with a darker culmen and base, their iris deep brown to red-brown, and their legs dark gray. Juveniles are duller and browner than adults and with more barring on the flank.
Taxonomy
The black-bodied woodpecker's taxonomy is unsettled. The South American Classification Committee (SACC) of the American Ornithological Society, the International Ornithological Committee, and the Clements taxonomy place it in genus Dryocopus. BirdLife International's Handbook of the Birds of the World (HBW) places it in genus Hylatomus. Further, the SACC spells the specific epithet schulzi, rejecting the change from it to schulzii that the other three systems adopted.<p>All four systems agree that the black-bodied woodpecker is monotypic.

Range and habitat
The black-bodied woodpecker is found from the southern Bolivia departments of Santa Cruz and Tarija south through western and central Paraguay into north-central Argentina as far as Córdoba and San Luis provinces. It inhabits the woodland and savanna of the dry Gran Chaco and the transition zones between them and moister montane forest. In elevation it ranges as high as 1,000 m (3,300 ft).

Behavior
The black-bodied woodpecker is a year-round resident throughout its range.<p>The black-bodied woodpecker usually forages singly or in pairs, but also occasionally in small family groups. It pecks, hammers, and probes trunks and main limbs. Its diet has not been described.<p>The black-bodied woodpecker's breeding season spans at least October to December and might extend to March. It excavates a nest hole in a dead tree or utility pole. The clutch size, incubation period, time to fledging, and details of parental care are not known.<p>The black-bodied woodpecker's most common call is "a loud “wic wic wic wic wic”". It also makes a "harsh rattle, “ti-chrr”", and when disturbed near its nest a repeated "descending “kirrrrrr”". It drums in a long roll.

Blackish Oystercatcher
Haematopus ater
Distinctive large chunky shorebird of rocky coasts, adjacent sandy beaches and river mouths. The only all-dark oystercatcher in South America, readily identified by wholly dark plumage, long orange-red bill, thick pinkish legs. Found as singles and pairs, less often small flocks (mainly when roosting), and associates readily with Magellanic and especially American Oystercatchers. Loud piping whistles sound similar to American Oystercatcher.
Rhinoceros Hornbill
Buceros rhinoceros
Majestic and stately inhabitant of mature lowland and foothill forests. Pitch black with a white tail marked by a single dark bar. Enormous bill is bright orange with a prominent casque that is short and rectangular in females, long and upswept in males. Often seen in powerful flight over forests, typically in pairs or small groups. Gives low, resonant calls, usually in series: either a single-syllabled “rohh” or a disyllabic “roh-ow.”
Orange-fronted Plushcrown
Metopothrix aurantiaca
Small, yellowish-tan bird. Orange face is unique, but sometimes difficult to see; a more obvious field mark is its bright orange legs. Forages singly or in pairs in the canopy of secondary forest, especially along rivers. Does not usually join mixed-species flocks. Song is a series of very high notes, like a piculet but a little softer.
