Black-fronted Piping-Guan
Pipile jacutinga
Rare, threatened, and spectacularly-plumaged black-and-white guan with a long black tail. Head is striking with bold white eyering and shaggy white cap contrasting with its red and blue wattle, its blue, black-tipped bill, and its black face. Usually seen in the canopy of large and well-preserved patches of montane and lowland Atlantic Forest. The song is a high-pitched rising whistle, but also often makes distinctive wing-whirrs like other guans.

White-bellied Erpornis
Erpornis zantholeuca
Small, crested, yuhina-like bird, frequently seen as a part of mixed flocks in a wide range of forested habitats. Upperparts yellowish green, underparts dingy gray except for yellow undertail coverts and whitish throat. Forages mostly in the upper layers of vegetation, from which its loud “nay nay” call is often heard.

Bare-eyed Rail
Gymnocrex plumbeiventris
A large, long-billed rail with a bright chestnut head, neck, and back, olive-colored wings, a black rump and tail, and a gray undercarriage. Note the pinkish-red bare skin around the eye. Legs pinkish-red and bill olive. Pairs or small groups inhabit swampy riverside areas and lowland and hill forest. Very shy. In Aru Islands, overlaps with the much larger Chestnut Rail, but can be distinguished by reddish legs, chestnut head color, and black tail. Gives a dramatic, deep bellowing “kyow-kyow” call and piglike grunts.
