Rufous-vented Chachalaca
Ortalis ruficauda
A large, long-tailed, chickenlike, and ground-dwelling bird of scrub and woodlands. Brown overall with a buff-orange vent. Commonly runs from perceived threats but sometimes bursts into rapid short flight. Unique in Caribbean, but in northern South America Chestnut-winged Chachalaca is light underneath and lacks rufous in tail. Produces a variety of vocalizations, including a loud “wuck-a-wuck-wuck” that is given in a crescendo series, a quiet muttered “wuck-wuck-wuck…,” a loud and squeaky shrill call often heard as “yuck” that is produced singly or in a series, and a loud squeaky “zwick,” given singly or in rapid bursts.

These are medium-sized birds, similar in general appearance to turkeys, with small heads, long strong legs and a long broad tail. They are typically 53–58 cm long; the female weighs 540g and the larger male 640g. They have fairly dull plumage, dark brown above and paler below. The head is grey, and the brown tail is tipped rufous or white depending on race.

分布与栖息地
The rufous-vented chachalaca is a largely arboreal species found in forest and woodland, but it is also found in more open dry scrubby areas. This combined with relatively low hunting pressure, make it far less vulnerable than larger members of the family, notably curassows.

Sepia-capped Flycatcher
Leptopogon amaurocephalus
Inconspicuous small flycatcher of humid tropical forest and edge. Usually found at middle levels inside forest and also in adjacent clearings where sometimes suspends its nest under the eaves of buildings, including ruins. Mainly sits quietly and fairly upright; at times sallies to pick insects from foliage. Note the grayish face with a dark ear patch, dark brownish (sepia) crown, and buffy wing edgings. Call is a stuttering froglike trill, given infrequently.
Ultramarine Grosbeak
Cyanoloxia brissonii
Stunning dark blue bird with a huge bill. Male is mostly deep cobalt with paler highlights on the shoulder and eyebrow and a darker patch around the eye. Female is rich reddish-brown overall. Found singly or in pairs in scrubby wooded habitats, often near water. Can be skulky, preferring to forage in dense thickets. Occurs mostly in southeastern South America, with disjunct populations in Venezuela and Colombia. Compare with Blue-black Grosbeak, which doesn’t overlap much in range and is typically found in heavier forest.
Channel-billed Toucan
Ramphastos vitellinus
Large toucan, widespread across South American lowlands. Mostly black with a dark bill (although some populations have a yellow ridge on top of the bill). Significant plumage variation across range: throat color varies from white to orange; bare skin around eye varies from blue to red. In the western part of its range, appearance is very similar to White-throated Toucan, but note voice: a grating croak, not a clear yelp. Singles, pairs, or small flocks are found in the forest canopy, often around fruiting trees. Named for the groove along the upper part of the bill, which is difficult to see in the field.
