Madagascar Buttonquail
Turnix nigricollis
Tiny, complexly patterned quail-like bird. Female has rufous sides, gray underparts, and black facial markings. Male is duller and browner. Found on the ground in a wide variety of habitats, including grassland, scrub, spiny forest, and western deciduous forest. Somewhat shy, though more approachable than quail. The song is a quick, pulsing series of low “hwo” notes. Male is similar to female quail, but smaller, and has weaker and less direct flight when flushed.
识别特征
The Madagascar buttonquail is a stocky bird with a small head and short legs and tail. Both sexes are cryptically coloured; the male has a light brown head with black and white streaking and mottling, and a greyish-brown back and wings with fine dark barring and pale-edged feathers, the barring on the outer scapulars being bolder. The tail is greyish-brown with fine barring. The chin and throat are whitish, the breast cinnamon-buff with dark barring and the belly whitish. The bill is bluish-grey, the irises white or pale grey and the legs greyish. The female is more brightly coloured. The top of the head is blackish and the mantle brownish-grey with some dark barring and cinnamon feather-edges, interspersed with some plain grey-brown feathers, giving a chequer-board effect. There is a white moustachial stripe below which the chin and upper throat form a black bib. The breast is cinnamon-pink and the belly grey with faint barring. The juvenile resembles the male but is somewhat darker and more heavily spotted.
分类信息
The Madagascar buttonquail was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with grouse like birds in the genus Tetrao and coined the binomial name Tetrao nigricollis. Gmelin based his description on the earlier accounts by the French naturalists Mathurin Jacques Brisson and Georges-Louis Leclerc, Comte de Buffon. The Madagascar buttonquail is now placed in the genus Turnix that was introduced in 1791 by French naturalist in Pierre Bonnaterre. The genus name is an abbreviation of the genus Coturnix. The specific epithet combines the Latin niger meaning "black" with Modern Latin collis meaning "-necked". The species is monotypic: no subspecies are recognised.

分布与栖息地
This buttonquail is endemic to the island of Madagascar and is present over most of the island in suitable habitat. It is found in grassland, open woodland, clearings, glades, the edges of forests, sandy and bushy locations, weedy places and cultivated areas, especially where cassava is grown. It has been introduced to Mauritius, where it is now likely extinct and is present on Réunion and the Glorioso Islands, although it is unclear whether it is native there.

行为
The species is often seen alone or in small groups of up to four birds. If startled it may crouch to avoid detection, or may run away, but seldom flies unless danger is very close. Even then, it flies with rapid wingbeats for only a short distance. It forages by scratching in the plant litter like a chicken, leaving distinctive circular depressions. It mainly feeds on invertebrates and has a particular liking for termite larvae. One individual was found to have eaten snails, cockroaches, beetles, flies, bugs and caterpillars. It may also eat seeds.<p>As with other members of this family, the female plays the more active role in the breeding season, defending a territory and making vocalisations to attract a male. The nest is built in a slight depression on the ground often concealed in a grass tussock or thick vegetation. It is built by both birds from dried grasses and stems, dead leaves and sometimes feathers. It may be partially roofed with dead leaves and sometimes is approached by a covered runway. A clutch of about four, heavily blotched eggs is laid. The male incubates these for about a fortnight, possibly being relieved by the female occasionally; he is also responsible for the care of the young, feeding them for the first week from his bill before they start to peck food from the ground. The female is at first aggressive towards the chicks and the male defends them, but later the female takes on more of a caring role. The chicks become independent by the fifth week and may be driven away by the parents after this.

Rio Branco Antbird
Cercomacra carbonaria
A slender, long-tailed bird of dense gallery forests and river islands in northern Brazil and extreme southwestern Guyana. Male is mostly black with tail feathers tipped white and with white scalloping on wings. Female is very different: brownish-gray above and buffy below, with a black tail and white throat streaked black. Like other Cercomacra, tends to stay concealed in dense vine tangles in the canopy and midstory, where it clambers slowly about, usually in pairs, searching for insects. Best detected by voice; two-noted song is given in series of 3–5 phrases, with hiccupping effect; similar to song of Gray Antbird but higher-pitched, faster, and less hoarse. Female is unlike any other species in range. Male is darker than Gray and Blackish antbirds, which do not occur in the same habitat and have different voices. Plumage recalls Dot-winged Antwren, but Rio Branco Antbird is considerably larger.
Tawny Antpitta
Grallaria quitensis
Medium-sized antpitta found in elfin forest and páramo near or above treeline in the Andes from western Colombia to extreme northwestern Peru. Typical antpitta shape: plump with short tail and long legs. Dull brownish plumage, darker above and buffier below. Sexes similar. Fairly common and much more conspicuous than most other antpittas; frequently seen bounding around in the open, though typically close to shrubby cover. Sometimes sings from a fairly prominent perch; listen for three piping whistles, a high first note followed by two lower notes.
Gray-throated Barbet
Gymnobucco bonapartei
Dark, chunky barbet with an odd tuft of feathers on its forehead. The eye is pale in the eastern part of the range and dark in the west. Usually in small groups on and around dead trees in humid forest and secondary growth. The vocalizations include nasal “squeaky toy” calls, “peet” notes, and a dry rattle. Similar to Naked-faced and Bristle-nosed Barbets, but has a mostly feathered head and a dark bill. Sladen’s Barbet also has a dark bill, but Gray-throated is separated from that species by its feathered head.
