White Bellbird
Procnias albus
Medium-sized bird; heard far more than seen. All-white male is unmistakable; mostly green female is best identified by chunky proportions and long, sloping head profile. Found in tall forest, principally at higher elevations; common in the tepui region. Feeds at fruiting trees but is more often seen from high vantage points or flying across gaps. Males sing from bare snags above the canopy and are often not visible from below. Song is only vaguely bell-like, amazingly loud and reverberating; younger males may give a cracked or truncated version.
识别特征
The white bellbird grows to a length of about 28 cm (11 in). The male is pure white with a black bill that has a fleshy black wattle, sparsely feathered with white feathers, dangling from its top and hanging down the side, usually the right side; the female is an overall olive colour, with olive streaks on the yellowish underparts, and resembles other bellbirds. The male is unlikely to be mistaken for anything else, but the female resembles the bearded bellbird (Procnias averano); that bird has a dusky olive crown and black streaking on the throat.<p>According to a study published in 2019, the white bellbird produces the loudest call ever recorded in a bird, reaching 125 dB(A) (at equivalent 1m distance). The record was previously held by the screaming piha, which was recorded at 116 dB.

Black Manakin
Xenopipo atronitens
Small bird of dry scrub enclaves in rainforest regions. All-black male is distinctive; compared to other manakins, note longish tail and blue bill in both sexes. Locally common in low-stature forests and savanna scrub woodland, always in areas with extremely weathered, sandy soil. Eats fruit. Groups of males give vocal displays from dispersed perches, often well inside vegetation. Male resembles Amazonian Black-Tyrant, but has shorter bill and is unlikely to occur in the same habitat. Most common call is an unusual, squeaky chuckle; useful when searching for this bird in dense scrub.

Rufous-fronted Tailorbird
Orthotomus frontalis
A small, long-billed, long-tailed bird of dense tangled undergrowth in lowland forest. Has olive-green wings, back, and tail, a pale belly, a gray head and chest with streaks, a rufous forehead and mask, and orange legs. Similar in habits and shape to White-browed Tailorbird, but lacks the black head and white brow. Also similar to Phillipine Leaf-Warbler, but has a longer bill and usually cocks its tail. Song is an accelerating series of slightly rising notes ending in a staccato trill.

Orange-bellied Leafbird
Chloropsis hardwickii
The only leafbird within its range with an orange belly. Male is unmistakable with a blue-and-black face pattern, a solid orange belly, and green-and-blue wings. Female is green all over with blue cheeks and less extensive orange on the belly. The female can be confused with female Blue-winged Leafbird, but Orange-bellied has an orange belly and more blue on the face than Blue-winged Leafbird. Often moves about quietly in the upper layers of hilly and montane forests, gleaning insects from branches and foraging at fruiting and flowering trees. Frequently incorporates the songs and calls of other species into its vocalizations.
