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.

Plumbeous Ibis
Theristicus caerulescens
Distinctive gray ibis with a white forehead and bushy crest. Favors marshes, rice fields, and ponds, but also occurs in grassland, pastures, and savanna. Eats insects, snails, and fish. Mostly seen singly or in pairs. Very vocal, especially at dawn, giving a fast series of cackling notes: "kah-kah-kah-kah-kah-kah-kah."
Ash-throated Casiornis
Casiornis fuscus
Large rufous flycatcher with a slight crest, a cinnamon back, dusky flight feathers, and buff underparts. Inhabits wooded caatinga (dry scrubby forest) in the breeding season, with migrants also found in Cerrado and Amazonian savannas and light woodland in the non-breeding season. The similar Rufous Casiornis has a rufous back, the same color as the wings.
Asir Magpie
Pica asirensis
A crow-like bird with a long, narrow tail. Flashy black-and-white pattern distinctive within range. An endangered species, this is a rare but conspicuous bird of juniper forest and riverine scrub between 2200–3000m in the Asir massif of southwestern Saudia Arabia, where it typically moves in pairs and small family groups. Very vocal, often giving loud querulous grating “kuaynk-kuaynk” calls and high-pitched woodpecker-like “keenk” notes. Does not overlap in range with Eurasian Magpie, but Asir has less white in the plumage, a larger bill, and a shorter tail.
