Slaty-breasted Tinamou
Crypturellus boucardi
A furtive, almost tailless game bird that lives on the ground in humid tropical forest of lowlands and foothills. Rarely seen (sometimes crosses quiet roads or trails), but mournful drawn out song is often heard, especially early and late in the day. Plumage is dark overall with a grayish neck and breast; female has distinct barring on upperparts. Prefers humid forest, rather than drier habitats where Thicket Tinamou is found.
识别特征
The slaty-breasted tinamou averages 27 cm (11 in) in length, and weighs about 470 g (1.04 lb). Its back and head are black to chestnut in color, brown on its wings, slaty grey on its breast, white on its throat, grey-brown on remainder of its underparts with darker barring on flanks and undertail. The female has barring on its wings. Its legs are pink to bright red, and its bill is dark above and yellow below.
分类信息
All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds.<p>The slaty-breasted tinamou has two sub-species: <p>Philip Sclater identified the slaty-breasted tinamou from a specimen from Oaxaca, Mexico, in 1859.

This species ranges along the Gulf of Mexico coast from southern Mexico, from southern Veracruz and northern Oaxaca south, to northern Costa Rica. Mexico, Belize, Guatemala, Honduras, Nicaragua and Costa Rica.<p>It prefers thick evergreen forests with thick undergrowth, but also can be found in thick forests with little undergrowth, secondary forests, and on regenerating plantations.

行为
It is a shy and difficult tinamou to be seen on the dark forest floors. Its call is a three-note call and lower than other tinamous. Its calls can be in long bouts, up to five hours at a time. This tinamou and the thicket tinamou will produce hybrids on occasion.<p>Like other tinamous, it feeds on fruit and seeds and some invertebrates, in particular, ants and termites.<p>The slaty-breasted tinamou male attracts 2 to 4 females to lay in its nest on the ground and in thick vegetation or between the raised roots of a tree. The male incubates and raises the young. Females will mate with more than one male.
保护状况
The IUCN has classified the slaty-breasted as vulnerable and it has an occurrence range of 330,000 km2 (130,000 sq mi). It is hunted for food but its numbers seem to be consistent.

Red-shouldered Spinetail
Synallaxis hellmayri
Angry-looking bird with a long spiky tail and brown plumage contrasting with a black throat and a rusty shoulder patch. Occurs in arid, scrubby woodlands where normally forages on or close to the ground. The song is a repetition of a short, fast “quebéc.”
Rufous-headed Tailorbird
Phyllergates heterolaemus
A small, long-billed, long-tailed bird of montane forest and scrub on Mindanao, with an olive back, wings, and tail, a yellow belly, a rufous head, and a pale buff throat and chest. Often cocks its tail. Juvenile has an olive rather than rufous head. Similar in shape and habits to other tailorbirds on Mindanao, but occurs at higher elevations, and has a yellow belly and rufous head. Song consists of very short, well spaced, varied phrases of fairly long, high-pitched piping notes.
Sooty-crowned Flycatcher
Myiarchus phaeocephalus
Fairly large flycatcher found mainly in dry forest in western Ecuador and northwestern Peru. It has a gray-brown crown (often raised to look “bushy”), an ashy throat, and a yellow belly. Dark head helps distinguish it from kingbirds. This species is one of many in the genus Myiarchus, members of which are notoriously difficult to identify by plumage alone; this is the only one in most of its range that prefers dry forest, but it overlaps with Brown-crested Flycatcher in the Marañon drainage. Sooty-crowned has a grayer crown and more chestnut in the wings and tail. Calls include a nasal, whiny whistle, a short rasp, and a creaky “wi-dit.”
