Rough-legged Tyrannulet
Acrochordopus burmeisteri
Small flycatcher found in forest canopy. Confusingly similar to other tyrannulets, but note especially its stubby (not pointy) bill with a very pale base, which can be quite evident since you are often looking straight up at the bird. Voice is another good clue; it often gives sharp whistles, either alone or in a series. It also tends to be more sluggish, perches more vertically, and stays higher up in the trees than other similar tyrannulets. It has two separate populations, one in the Atlantic Forest region, and another along the east slope of the Andes in Argentina, Bolivia, and perhaps far southern Peru. Northward it is replaced by White-fronted Tyrannulet, which is now considered a separate species. The area of overlap is not well known. Rough-legged Tyrannulet is more uniformly colored, showing little or no gray in the crown.

Chabert Vanga
Leptopterus chabert
Small, black-and-white finch-like vanga. Shows a white patch at the base of the tail in the southwest, and an all-black tail elsewhere. Madagascar endemic that is found in all forest types, and sometimes in plantations and scrub. Constantly on the move, usually in small flocks. Frequently gives a dry “cha-bert” call. Smaller than White-headed Vanga, with a black cap. Also smaller than Blue Vanga, with a black rather than blue back.
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.
Variable Limestone Babbler
Gypsophila crispifrons
A large, chunky, scraggly-looking babbler found in limestone hills covered with forest. Gray and brown overall with heavy streaking on the head, back, and throat. An odd white morph shows a variable amount and distribution of bright white on the head and breast. Forages close to the ground, often in and around rocky cracks and crevices. Song is a loud, ringing, rather hoarse-sounding sequence of whistled notes including some repeated phrases, sometimes given as a duet by a pair. Also gives harsh “grrr” calls. Similar to Streaked Wren-Babbler, but larger and longer-tailed, lacking white spots on the shoulder.
