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.
Identification
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.
Taxonomy
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.

Range and habitat

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. It likes moist areas as well.

Behavior
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.
Conservation
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.

Sinaloa Martin
Progne sinaloae
Large swallow; very local summer resident in mountains of northwest Mexico. Favors open pine-oak forest, usually with big dead pine snags and cliffs, where nests in cavities. Ranges widely in highlands and foothills, coming to drink at ponds and lakes. Usually seen as singles or small groups, which may associate with other swallows. Male blue-black overall with contrasting white belly. Female similar to several other martins, but clean white belly contrasts more strongly with dark breast.
Solitary Tinamou
Tinamus solitarius
Large, dumpy, almost tailless terrestrial inhabitant of the Atlantic Forest, where it walks quietly through forests with an open understory. This tinamou has a gray-brown barred back and vent, pale gray on the belly with a prominent pale stripe on the side of the neck. Very secretive, best identified by song, a series of “frru” whistles with long silences between them.
Palawan Scops-Owl
Otus fuliginosus
A fairly small owl of lowland forest. Dark brown above with a white bar behind the shoulder, and paler and warmer brown below with black marks. Note the wide, shallow V-shape stretching from between the eyes out to the ends of the prominent ear tufts, and the dark facial shield incompletely bordered with white below. Eyes are deep orange. Similar to Mantanani Scops-Owl, which only occurs on small offshore islands off Palawan, but differs in eye color. Voice is a low rasping croak, “gruk grrrrrrrrr.”
