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.

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.

White-winged Dove
Zenaida asiatica
Bulky, grayish-brown dove with conspicuous white patch on wings. When perched, the white patch looks like a line along the bottom edge of the wing, but it is more obvious in flight, contrasting with the dark outer wings. Also look for bold white tips on tail feathers. Heftier and shorter-tailed than Mourning Dove. Also compare with Eurasian Collared-Dove; White-winged is darker and more contrasty on the wings and tail. Found in deserts, fields, cities and suburbs, and open wooded habitats from the southern U.S. to Panama (including the Caribbean). Usually common, sometimes traveling in large flocks, especially in winter. Visits backyard feeders.
Azure-rumped Tanager
Poecilostreptus cabanisi
Small, very local tanager of humid Pacific-slope foothills in Chiapas and Guatemala. Found in evergreen forests and adjacent shade-coffee plantations. Usually in pairs or small groups that forage at all levels, but often in the canopy of taller trees. Sexes look alike: pale bluish overall with contrasting black shoulders and black spotting across the breast. In good light, varied lilac, green, and turquoise sheens are apparent on the upperparts.
Mayr's Swiftlet
Aerodramus orientalis
A grayish-brown swiftlet, paler beneath, darker above with a faintly bluish tinge, with a variably grayish rump. Very poorly known from a few specimens and field observations. Generally occurs between 900-1200 meters of elevation, but has been seen at sea level. Very similar to White-rumped Swift, but has a darker gray rump and is much larger. Vocally unknown.
