Black-fronted Piping-Guan
Pipile jacutinga
Rare, threatened, and spectacularly-plumaged black-and-white guan with a long black tail. Head is striking with bold white eyering and shaggy white cap contrasting with its red and blue wattle, its blue, black-tipped bill, and its black face. Usually seen in the canopy of large and well-preserved patches of montane and lowland Atlantic Forest. The song is a high-pitched rising whistle, but also often makes distinctive wing-whirrs like other guans.
识别特征
The black-fronted piping guan is 63.5 to 74 cm (2.08 to 2.43 ft) long and weighs 1,100 to 1,400 g (2.4 to 3.1 lb). It is similar in general appearance to a slim turkey, with a thin neck and small head. It is mainly black with a bluish gloss and a conspicuous white wing patch bearing rows of black dots. It has a large white crest and a red throat wattle with a dark blue patch at the front. Its ring of bare white skin around the dark eye and black-feathered face and forehead are unique in its genus. The legs and feet are red.
分类信息
The taxonomies of the International Ornithological Committee (IOC), The Clements Checklist of Birds of the World, and Handbook of the Birds of the World treat the black-fronted piping guan as one of four species in genus Pipile. Though also agreeing with this treatment, the South American Classification Committee of the American Ornithological Society notes that "evidence for species rank for the four species of Pipile is weak". Various authors have proposed instead that the genus contains one, two, or three species, or that it should be subsumed entirely into genus Aburria with the wattled guan (A. aburri).<p>As currently accepted, the black-fronted piping guan is monotypic.

分布与栖息地
Though it was formerly more widespread, the black-fronted piping guan is now found spottily in two general areas. It ranges near the Brazilian coast roughly from Paraná state north to Rio de Janeiro and also in Argentina's far northeastern Misiones Province and adjacent eastern Paraguay. It is the only piping guan in this range though formerly it overlapped a small amount with blue-throated piping guan (P. cumanensis) in Paraguay. It inhabits several types of Atlantic Forest including evergreen, gallery, and coastal. It is almost always found in mature primary forest though also in older secondary forest and restinga. In elevation it formerly ranged from sea level as high as 1,850 m (6,070 ft) but now is usually found only below 1,000 m (3,300 ft)

行为
Some altitudinal and seasonal movements by the black-fronted piping guan have been documented, though the reasons for them are not clear.<p>The black-fronted piping guan forages alone, in pairs, or in groups as large as 11, usually in trees but sometimes on the ground. Its diet is primarily fruit, and studies in Brazil have documented 41 species eaten there. It will occasionally eat seeds, buds, insects, and molluscs. It tends to remain in an area of fruiting trees until they are bare.<p>The black-fronted piping guan's breeding season appears to span at least August to December based on the dates of observations of displays, eggs, and nestlings. Their nest is a platform made of twigs and stems placed in the fork of a tree. The clutch size is two to four eggs. Almost all incubation is by the female but both sexes provision young.<p>The black-fronted piping guan's primary vocalization is a "series of thin, rising whistles similar to those of congenerics". Its alarm call is also similar to that of other Pipile but with a more metallic tone. A dusk and dawn wing-whirring display has "two silent wingbeats, a long dry rattle, two more quick wingbeats and finally an even longer rattle".

Jackson's Hornbill
Tockus jacksoni
A medium-sized black-and-white hornbill. Males have a mostly red bill with a small yellow or white tip; females have an all-black bill. Both sexes show white spotting across the wing. Found locally in dry savanna, usually in pairs or small groups. Similar to Von der Decken’s and Northern Red-billed Hornbills, but separated from the former by the white-spotted wing and from the latter by the yellow-tipped (male) or all-black (female) bill. The call is a series of low clucks.
Northern Bobwhite
Colinus virginianus
Small and rotund with intricate brown, black, and white patterning. Some striking variation in plumage across range. Most males, including those in the eastern U.S., have bold black and white head pattern and heavy white spotting on belly. In Mexico, males can be entirely cinnamon-colored below and have a fully black head; some might have a white eyebrow or a dark chest band. Females are more consistent throughout range: look for buffy throat and eyebrow. Pairs or small groups are found in scrubby fields and brushy woods. Usually on the ground, but occasionally perches in trees when singing. The only quail native to the eastern U.S., where populations are declining sharply. Listen for distinctive “bob-WHITE!” whistle.
Yellow-throated Toucan
Ramphastos ambiguus
Large conspicuous bird with oversized bill. Mostly black overall with yellow throat and face. Note bicolored bill: dark below and yellow above. Found in pairs or small groups, often parading through the canopy in search of fruit. Sometimes perches very obviously at the top of a tree. Favors forested areas, but can also be found in gardens and edges. Yelping call helps distinguish from similar looking species.
