This seedeater has a widespread but disjunct range throughout much of Central and South America. Males are mostly slaty gray with a paler belly and whitish patches on side of the neck and base of primaries. Note stout yellow bill with curved upper mandible. Females are brownish, similar to other seedeaters, but note stout dark bill and whitish belly. Generally rare and irregular. Usually occurs in small flocks at forest edge, occasionally venturing into more open habitats. Sometimes associated with seeding bamboo.

Gray-eyed Bulbul
Iole propinqua
Drab, undistinguished-looking bulbul. Predominantly gray-brown with a white throat and slight rufous tones on the wings and tail. Pale eye and unmarked head distinguish it from other plain brownish bulbuls within its range. Tends to be seen solitarily or in pairs but will occasionally join mixed flocks or forage in larger groups at fruiting trees. Unmusical; gives a loud, ringing nasal note, often repetitively.
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.
Mariana Swiftlet
Aerodramus bartschi
A tiny, all-dark swift. Flight is fast, fluttery, and batlike. Usually observed flying continuously along ridges or over the forest canopy. Native to the Mariana Islands; introduced to Hawaii from Guam in the 1960s. In Hawaii, occurs only in the mountains of Central Oahu, seen primarily in Halawa Valley and the adjacent Aiea Loop Trail.
