Red-eyed Bulbul

Skulking warbler of grassy areas such as overgrown fields and marshes. Male has a striking black bandit mask, and his gray crown helps to separate him from other yellowthroats in range. Female is plain and confusing; she is yellower on the belly than female Common Yellowthroat, and tends to have darker upperparts than Olive-crowned Yellowthroat. Female also similar to female Yellow Warbler, but has a thicker bill and darker back. Song is a rather variable series of sweet whistles; also give a short, descending churr. Pairs usually stay hidden in dense vegetation. Males occasionally come up to sing or call from a more exposed perch. Note its range; after a taxonomical update, this species ranges only in northern South America.

A small, attractive shrike with a rufous back and rump, a gray cap and neck, and a black mask through the eyes. Usually shows a small white patch on the front of the wing. Uncommon and local in moist savanna habitats, usually in pairs or small groups. Not very vocal, but does give a series of whistles and low, scratchy notes. Similar to migratory Red-backed Shrike, but smaller, with a rufous rather than gray rump. 

A distinctive malimbe of lowland forests, particularly favoring lowland swamps with palms and areas near water, often in the understory. Overall glossy black with a triangular red throat patch and a pale gray-blue bill. Occurs in small groups or with mixed-species flocks, sometimes with other species of malimbe. The only malimbe with a combination of entirely dark upperparts, red throat, and black vent. Song includes whistled and mechanical notes with rasps, and calls include short rasping “rhewp” notes.
