Trinidad Piping-Guan
Pipile pipile
Large, turkey-like bird found only in the forests of northern Trinidad. It is black with white patches on the wings and crown, a light blue face, and an azure dewlap (flap of bare skin) that dangles from its throat. It is usually seen high in the trees, but on rare occasions can descend to the ground. Song is a series of drawn out, rising whistles, and it also sometimes rattles its wings loudly in flight. Locally known as “pawi”, this impressive bird is highly endangered due to hunting, and is regularly seen in only a few places, such as near the town of Grand Riviere.
识别特征
This is a medium-sized cracid, 60 cm in length, and similar in general appearance to a turkey, with a thin neck and small head. It is mainly black with a purple gloss. The large crest is blackish, edged with white, and there are large white wing patches. The bare face and wattle are blue, and the legs are red.<p>The Trinidad piping guan's call is a thin piping. The wings whirr in flight.
分类信息
Data confirms that the other blue-wattled species, the blue-throated piping guan, is the Trinidad species' closest living relative. The same data suggests that these diverged some 400,000 years ago at latest, perhaps as early as 1.6 mya, whereas Trinidad has been an island only since the end of the last ice age. This indicates that the Trinidad piping guan evolved in mainland South America, being driven to its relict island range in more recent times. The holotype of this species was supposedly collected in the "Orinoco River [region] near Cumaná" (del Hoyo 1994a,b). This locality has usually been considered erroneous. However, as it indicates an area on the mainland roughly opposite Trinidad, it might actually be correct and indicate that the Trinidad piping guan was not extirpated from Venezuela until around 1800. In South America, the form cumanensis has a greenish gloss to the plumage, a white face and crest, and a blue wattle, cujubi has a blue face and a red wattle, and jacutinga has a black face and a red wattle."

行为
They are forest birds, and the nest is built in a tree. Three large white eggs are laid, the female alone incubating. This arboreal species feeds on fruit and berries (such as those from the fragrant nutmeg and baboonwood), as well as flowers and leaves. The confirmation of small insects being a part of their diet has not been made yet.

White-browed Bushchat
Saxicola macrorhynchus
A small stonechat-like bird with a relatively long, slim bill. Male has blackish upperparts, a dark face, a white chin, and a whitish, contrasting eyebrow. Breeding males are darker and more contrasting overall than nonbreeding males. Females are brownish overall, with pale underparts, a pale eyebrow, and a lightly streaked brown back. Both sexes often forage on the ground, where they perform a strange “puff-and-roll” display, which involves puffing out the chest and moving from side-to-side. Rare, found in dry, arid scrubland.
Baglafecht Weaver
Ploceus baglafecht
Large, chunky weaver with a long, heavy bill. Extremely variable geographically. Always shows a pale eye, some black on the face, a yellow breast, and yellow edges on the wing feathers. The color of the crown can be yellow, black, or olive. The back varies from plain olive to heavily-streaked olive to solid black. The belly can be yellow or white. Found mainly at middle and high elevations, in woodland, moist scrub, gardens, cultivation, and forest edge. Vocalizations are typical of weavers: “chet” notes and a sizzling, “radio static” song. Highly variable, and can be confused with several other weaver species, but can usually be identified by combination of black face, yellow throat, and large size.
Collared Imperial-Pigeon
Ducula mullerii
The large, nomadic pigeon of mangroves and riverine forests. Note the distinctive, full black collar that narrows at the front and meets the maroon back. Black tail with white band across. Small flocks often seen in flight or perched up on exposed branches. Unmistakable when seen perched, but in flight similar to Pinon’s Imperial-Pigeon. Collared Imperial-Pigeon is much more likely in mangroves. Call, a deep, muffled “woo-oo pooo” with the first 2-note call falling and the last, lower in pitch.
