Black-spotted Barbet
Capito niger
Medium-sized sluggish bird of rainforest canopy. From below note size and sharply demarcated red throat on both sexes. Also occurs in secondary forests and overgrown plantations, sometimes in urban areas. Often seen in pairs at fruiting trees or with mixed-species flocks. Forages slowly and deliberately, feeding on fruit and insects. Often-heard call is a low-pitched, doubled hoot, repeated in series.
识别特征
The black-spotted barbet is 16 to 19 cm (6.3 to 7.5 in) long and weighs 41 to 68 g (1.4 to 2.4 oz). It is intricately colored, with much variation in the richness of the colors. The adult male has a red forehead, a yellowish crown and nape, and a black band from the lores to the nape. The nape has dusky streaks. Its upperside is black; its mantle is outlined yellowish and it has yellowish wingbars. Its throat is red, the breast and belly yellow, and the flanks yellow with an olive tinge and black streaks. The adult female is similarly colored but more heavily marked; its upperparts have pale flecks on the black and the breast and belly are spotted or streaked. The immatures are similar to the adults but duller.
分类信息
Until the late 20th century, the black-spotted barbet was often considered to be a subspecies of the widespread gilded barbet (Capito auratus). The black-spotted, gilded, and brown-chested barbets (C. brunneipectus) apparently form a superspecies.<p>As it is currently defined, the black-spotted barbet is monotypic.

分布与栖息地
The black-spotted barbet is found in the eastern parts of Venezuela's Bolívar and Delta Amacuro states, the three countries of the Guianas, and the Brazilian states of Roraima, Pará, and Amapá north of the Amazon River. It inhabits the interiors of a variety of forest types including terra firme, riparian, and várzea. It also uses the forest edges and more open terrain such as gardens and plantations. In elevation it ranges from sea level up to 200 m (660 ft) in Venezuela and as high as 800 m (2,600 ft) in the Guianas.

行为
Though little is known about the black-spotted barbet's diet and foraging habits, they are assumed to be similar to those of the gilded barbet.<p>The black-spotted barbet breeds from September to May and possibly to July. Pairs excavate a cavity in a tree 5 to 12 m (16 to 39 ft) above ground. The female lays three or four eggs and both parents incubate them.<p>The black-spotted barbet's song is "double, sometimes single, low 'wú-woot' notes" [1]. Its call is a scratchy croak [2].

Purple-throated Cotinga
Porphyrolaema porphyrolaema
Striking, ornately-colored cotinga. Male and female are uniquely beautiful: males are black above, white below, with a bright purple throat and breast; females are tawny yellowish with extensive black barring. Found in the canopy of mature rainforest; seemingly preferentially around water. Its song is a mellow whistled “wheeeu”, which sounds similar to several other species like Cinereous Mourner and Chestnut-capped Puffbird.
Australian Tern
Gelochelidon macrotarsa
Medium-sized tern with thick black bill. Very pale overall with black cap in breeding plumage. Legs black. Nonbreeding plumage shows small dark cheek patch. Found both coastally and inland in a variety of wetland habitats, including beaches, mudflats, freshwater marshes, and even wet fields. Occasionally joins flocks with other terns, but more often seen singly or in pairs. Graceful in flight; swoops over ponds and marshes where it grabs invertebrates from the surface. Formerly considered part of Gull-billed Tern, and limits of the range of that species and Australian in New Guinea and southern Indonesia poorly understood.
Common Snipe
Gallinago gallinago
Squat, cryptically-plumaged shorebird with a very long bill. Inhabits a wide range of wetland habitats, from damp meadows to saltmarshes. Mostly inconspicuous, feeding in muddy ground by probing with its bill, usually near reeds or other grassy cover. Often not seen until flushed, when it usually rises from fairly close range with a rough rasping call. Breeding birds are more conspicuous, perching on fence posts. In display flight, birds stoop from high overhead and produce a pulsating, bleating sound from air passing through their fanned tail. In Asia, beware of extremely similar Pin-tailed, Swinhoe's, and Latham's Snipes, all of which lack the white trailing edge of Common and have a slower, less erratic flight.
