Fülleborn's Boubou
Laniarius fuelleborni
Mid-sized bushshrike that is completely black. Found in the undergrowth of humid forest at middle and high elevations. A skilled skulker that is most often detected by voice. Gives a wide variety of vocalizations, which include whistles, explosive notes, frog-like calls, and ratchets. The most common vocalization is a quick series of three whistles: “whit-whit-wee.” Very similar to Slate-colored Boubou, but found in montane forest rather than lower-elevation savanna and woodland.
识别特征
Fülleborn's boubou is a medium-sized boubou, growing to a length of 18 to 20 cm (7 to 8 in). The sexes are similar and the adult plumage is a bluish slate-grey with a blacker head, wings and tail, all of which are slightly glossed. The underparts are dark slatey-grey and the underwing is dark brown. The eye is brown or reddish-brown and the beak and legs are black. The upper parts of the juvenile are a brownish-black colour, faintly spotted with buff, and lacking gloss. The underparts are barred with buffy greyish-black. The adult plumage is gained at six or seven weeks. This boubou only takes to the wing occasionally and has a ponderous flight.
分类信息
This bird has often been considered to be conspecific with the mountain sooty boubou (Laniarius poensis) complex (including the albertine sooty boubou (Laniarius holomelos) and Willard's sooty boubou (Laniarius willardi)), but Fülleborn's boubou possesses a different juvenile plumage of that complex, as well as differing morphologically and with respect to vocalizations. Recent genetic studies also indicate the two species are closely related but do not form a superspecies. Fülleborn's boubou is also similar to the slate-colored boubou (Laniarius funebris), but they occupy different ecological niches.

Yellow-vented Woodpecker
Dryobates dignus
Fairly small woodpecker found in subtropical Andean forests from Colombia to Peru. Generally uncommon and inconspicuous as it feeds in the middle to upper levels of the trees, sometimes with a mixed-species flock. Look for bold face pattern: white eyebrow and mustache separated by dark cheek, and red crown (restricted to nape in female). Underparts pale yellow with bold dark barring. Not many similar species at the same elevation.

Golden-spangled Piculet
Picumnus exilis
Tiny bird of forest canopy; best identified by stub-tailed appearance, conical bill, and behavior. Occurs in upper levels of rainforest and patches of tall forest in savanna regions. Often found with mixed-species flocks. Taps vigorously into fine dead twigs and vines, often hanging upside-down at the ends of branches. Similar to White-barred Piculet but occurs in different habitat and has finer barring on belly, giving an overall darker appearance. Most frequent call is two soft squeaks, the second lower-pitched.

Obi Paradise-crow
Lycocorax obiensis
A large, blackish, crow-like bird-of-paradise, endemic to Obi and Bisa. Body is entirely blackish with paler, browner wings. Also often shows a thin line behind the eye. Shape is distinctive, with thin neck and small head with distinctive brow ridges. Juveniles are browner overall. Singles and pairs occupy canopy in forest, forest edge, and plantations in lowlands and hills. Brown cast to wings and head shape differentiate it from crows. In flight shows broad wings and an awkward, clumsy, hurried flight, unlike the slow flapping of crows. Calls include a trumpet-like “nyek”, an alien-sounding “nwoop”, as well as harsher rasping notes.
