Maroon-chested Ground Dove
Paraclaravis mondetoura
Very scarce and rarely seen small dove of foothill and mountain forest and edge, usually with patches of seeding bamboo. Most often seen in fast direct flight; rarely seen perched or feeding in low vegetation or on the ground. Male deep blue-gray with purple bands on the wings and a maroon breast; white outer tail feathers striking when tail is spread. Female with dark bill, and brown overall with dark reddish-brown bands on the wings; rump and tail less rusty than similar female Blue Ground Dove of humid tropical lowlands.
识别特征
Males of the maroon-chested ground dove are 18 to 24 cm (7.1 to 9.4 in) long and females 19 to 22 cm (7.5 to 8.7 in). Both sexes weigh between 89 and 95 g (3.1 and 3.4 oz). The adult male's forehead, face, and chin are grayish white. Its breast is dark purple changing to gray on the belly and vent. Its upperparts and wings are blue-gray, with the folded wing showing two broad dark bars. The central tail feathers are gray, the outermost white, and those between grayish white. Its orange eye is surrounded by bare yellow skin. The adult female is brown overall with a cinnamon face; the darker wing bars are not as distinct. The juvenile is similar to the adult female but redder. The putative subspecies differ slightly in their coloration.
分类信息
The maroon-chested ground dove was originally placed in genus Claravis but a 2018 publication created the current genus Paraclaravis for it and the purple-winged ground dove (P. geoffroyi). The International Ornithological Committee (IOC) and Howard and Moore taxonomies treat it as monotypic. However, the Clements taxonomy and the Handbook of the Birds of the World ascribe these six subspecies to it:<p>The Cornell Lab of Ornithology's Birds of the World account cautions that some of the subspecies were described from very small samples and may reflect individual, not subspecific, variation. It singles out P. m. inca as "doubtfully valid".

分布与栖息地
The maroon-chested ground dove is found discontinuously from southeastern Mexico to Peru and Bolivia. The subspecies are described as distributed thus:<p>The maroon-chested ground dove inhabits dense undergrowth in wet montane forest, its edges, and thickets of secondary forest. It is strongly associated with bamboo. In elevation it ranges between 1,200 and 2,500 m (3,900 and 8,200 ft) in Mexico, 900 and 3,000 m (3,000 and 9,800 ft) in Costa Rica, 1,000 and 2,100 m (3,300 and 6,900 ft) in Panama, and 1,300 and 2,600 m (4,300 and 8,500 ft) in the Andes.

行为
The maroon-chested ground dove forages on the ground for seeds and fallen fruit. Usually it forages alone or in pairs, but has been noted feeding in flocks of up to 15 birds. Bamboo seeds are a major component of its diet, and it will stay in an area only as long as its bamboo is seeding.<p>Little is known about the maroon-chested ground dove's breeding phenology, but it is suspected to nest in loose colonies. The one described nest was a simple platform containing two eggs, placed in Chusquea bamboo in the mountains of southeastern Ecuador.<p>The maroon-chested ground dove's song is "a series of low-pitched, slightly rising bisyllable coos 'cuWOOP.....cuWOOP.....cuWOOP...'".

Bornean Ground-Cuckoo
Carpococcyx radiceus
Secretive pheasant-like cuckoo that is more often heard than seen; listen for its dove-like “coo-KOO” song and odd sneeze-like call. Beautiful if seen well: iridescent purple-green wings, long dark tail, finely barred underparts, black head, and pale blue-green face and bill. Forages on the ground, often following ant swarms or Bornean bearded pigs as they flush out potential prey. Favors pristine lowland rainforests, particularly in riverine or swampy areas.
Somali Courser
Cursorius somalensis
A plain, pale courser with black lines behind the eyes that make a “V” when seen from behind. In flight, the wings are partially black with a white trailing edge. Found in dry savanna, thornscrub, and desert. Usually in small groups, which tend to flee from disturbance on foot. Very similar to Cream-colored Courser, but browner and shorter-winged, with partially pale rather than completely black underwings in flight. Fairly similar to Temminck’s Courser, but paler overall, lacks chestnut in the crown, and has a paler underwing. Calls include a quiet “whit” and a louder “trow.”
Magellanic Snipe
Gallinago magellanica
Cryptic shorebird found predominately in lowland wet grasslands and flooded fields. Note the long straight bill, white belly with variegated cryptic plumage, and prominent contrasting pale lines on the face and back. In flight, shows a white terminal tail band. Sings a repetitive “kek kek kek kek” when on the ground. Also listen for harsh and vibrating “drumming” notes given in stuttered couplets, produced with its tail feathers during flight displays. Occurs from central Chile to southern Argentina, extensively across the Patagonia region, including the Falkland Islands. Formerly known as South American Snipe.
