Bearded Bellbird
Procnias averano
Famously loud and distinctive-looking, this large cotinga is one of the iconic species of northern South America. Male is unmistakable with mostly white body, black wings, brown head, and throat full of dangling black wattles that look like the bird threw up a plateful of worms onto itself. Female is much plainer, greenish with faint yellow streaks on the underparts. Female is extremely similar to female White Bellbird; where range overlaps with White Bellbird, Bearded typically occurs at higher elevations. Most often found by the extremely loud and far-carrying “bonk!” call given by the male.
Identification
Like other cotingas, the bearded bellbird has a broad hooked-tipped bill, rounded wings, strong legs and a striking appearance. The male is approx 28 cm 11 in long, and weighs .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);clip-path:polygon(0px 0px,0px 0px,0px 0px);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}180 g (6+1⁄2 oz). His plumage is white or greyish-white apart from the black wings and warm brown head. He sports a "beard" of un-feathered, black stringy wattles.<p>The female is smaller, at approx. 27 cm (10+1⁄2 in) and 130 g (4+1⁄2 oz). Her upperparts are olive-green (duskier on the head), most of the underparts are yellow streaked with green, and the vent is pure yellow. She lacks the facial wattles ("beard"). Both sexes have dark eyes, a black bill and grey to black legs.<p>The males' advertising calls are a very loud dull Bock repeated every few seconds and a somewhat less loud, metallic hammering tonk-tonk-tonk-tonk. It sounds like a hammer rapidly hitting an anvil and is repeated 20–30 times. Additionally, a number of regional calls are known, e.g. an unmusical, almost hissing, bisset in southern Venezuela and a disyllabic teek-terong in northern Venezuela. Apparently, the last mentioned call is no longer heard in Trinidad. The female is essentially silent.

Range and habitat
The bearded bellbird is native to Venezuela (as well as adjacent parts of Colombia and Guyana), Trinidad and Tobago and northeastern Brazil, where it occurs in humid forests and woodland. It is mainly resident, but some populations take part in altitudinal migrations; breeding at altitudes of up to 1,900 m (6,200 ft) and spending the non-breeding season in the lowlands. There are two subspecies; the nominate taxon, P. a. averano, in northeastern Brazil and P. a. carnobarba in Venezuela, Trinidad, extreme northeastern Colombia, western Guyana and far northern Brazil. It is a localised and uncommon bird in Venezuela, but is fairly common in Trinidad. The nominate Brazilian race is relatively rare due to extensive habitat destruction in its range and heavy trapping for the cagebird trade, and as such is considered "vulnerable" by Brazilian environmental authority (IBAMA).

Behavior
These arboreal bellbirds feeds entirely on fruit and berries, mainly taken on the wing. Lauraceae and Burseraceae are particularly favoured (as well as Araliaceae and Melastomataceae), and the young are fed regurgitated Lauraceae by the female.<p>The flimsy nest of twigs is built by the female and usually placed in the outer branches of a tree. The nests are not located in the jungle, but in free-standing trees in semi-cleared areas, probably to reduce the risk from the many effective predators of nests in the jungle such as monkeys, toucans and snakes.<p>The single brown-mottled, light tan egg is incubated entirely by the female, leaving the polygamous male free to spend much of his time advertising with his distinctive songs. Laying season varies over its range; April-Nov in Trinidad and May-Sep in N. Venezuela. The first recorded egg was discovered near Cumaca, Trinidad, in the mid-1950s.

Other Birds
Baudo Guan
Penelope ortoni
Medium-sized turkeylike bird restricted to very wet rainforest in lowlands and foothills of western Colombia and northwestern Ecuador. It is dark brown with white streaks on the underparts and a red dewlap. Similar to the more common Crested Guan, but is smaller, browner (lacking chestnut on the belly and tail), and shows little or no crest. Baudo Guan is usually found in small groups high in the trees, and is very sensitive to habitat alteration; it is rarely encountered away from remote, relatively undisturbed areas.
Philadelphia Vireo
Vireo philadelphicus
Small, short-tailed, most similar to Warbling Vireo, but brighter: look for yellow wash on underparts, brightest on throat and undertail, and dark line through the eye that connects to base of bill. Dull individuals can be very difficult to distinguish from Warbling Vireo, but Warbling usually brightest yellow on flanks, not throat. Similar to Red-eyed Vireo but with shorter bill and yellower below. Breeds in deciduous forests, especially areas with younger trees including birches or aspens. Migrates through a variety of wooded and brushy habitats; winters in Central America. Song nearly identical to Red-eyed Vireo. Feeds on insects; especially caterpillars.
Marsh Babbler
Pellorneum palustre
A small, mostly brown bird with a heavily streaked pale breast. Note the white eyebrow, the white throat, and the rusty flanks and belly. Found in wetlands with dense grasses and reeds, where it is difficult to see as it forages for invertebrates. Best located by song, which includes a series of scratchy notes followed by 1-4 loud, musical whistles.
