Black Honey-buzzard
Henicopernis infuscatus
A distinctive raptor confined to New Britain. Entirely blackish-brown with indistinct dark markings and a beady pale eye. In flight appears long-tailed and broad-winged, with well-pronounced “fingers” on the outer wing; from below, note bold white bars on the tail, outermost wing feathers, and trailing edge of the wings. Juveniles resemble adults. Found in forest from lowlands to hills. Unmistakable in its limited range, where no other similar raptors occur. Call consists of a series of upslurred whistles, rapidly gaining in pace.
识别特征
The black honey buzzard is a dark grey-brown colour with pale silvery bars on the wings and tail. When perched, the wing and tail bars are clearly visible. In flight, the wing bars are notable and the wing shape is distinctive, with a narrow base and broad tips, and bulging outer primaries. Juvenile markings are unknown. Its height ranges 48–52 cm (19–20 in), and wingspan ranges 110–115 cm (43–45 in).<p>It was first identified and catalogued among European natural historians by James Sligo Jameson in 1877.
分类信息
The black honey buzzard belongs within the subfamily Perninae, in the family Accipitridae. The family Acipitridae contains two subfamilies of kites: Elaninae and Perninae. Birds within Perninae lack the bony eye shield that characterizes those in Elaninae, and are mainly found in the tropics where they are specialized to feed on insects, bee and wasp larvae.<p>The genus Henicopernis contains only two species: The black honey buzzard and the long-tailed honey buzzard (Henicopernis longicauda). The Australo-Papuan region, which encompasses Australia and Papua New Guinea, has many endemic species since the region was isolated from other land masses for millions of years. These include three closely related genera of the family Accipitridae: Henicopernis, Hamirostra and Lophoictinia.

分布与栖息地
The black honey buzzard occurs on the island of New Britain, part of the Bismarck archipelago in Papua New Guinea. Its habitat consists of primary rainforest, usually in hilly areas. Its altitudinal range extends up to 1,300 m (4,300 ft). The population is estimated to be between 6000 and 15 000 mature individuals.

行为
Its vocalizations consist of 12 piping notes, accelerating and shortening over about three seconds.<p>The diet is largely unknown, but it is assumed that it is similar to that of the long-tailed honey buzzard, which typically feeds on arthropods, lizards, birds and birds’ eggs.<p>The black honey buzzard is unobtrusive, and is seldom sighted due to its shy nature. Although the generation length has not been studied directly, it is estimated to be approximately 10 years, based on that of two similar-sized raptors: The square-tailed kite (Lophoictinia isura) and the red goshawk (Erythrotriorchis radiatus).
保护状况
The black honey buzzard is highly dependent on primary forest, where it nests and feeds. This species is estimated to have lost 12.5% of the primary forest within its range between the years 1990 and 2000. The island of New Britain has experienced considerable deforestation due to logging, as well as land use change as forested areas are converted to small-scale agricultural operations and oil palm plantations. In 2004, West New Britain province accounted for over 50% of Papua New Guinea's timber exports. However, a great deal of the species’ range is on steep and montane areas which are not suitable for logging or oil palm production.<p>The black honey buzzard is classified as vulnerable according to the IUCN Red List of Threatened Species. This classification is primarily due to the continuing decline the area of available habitat.

其他鸟类
Spot-throated Hummingbird
Thaumasius taczanowskii
A large, drab hummingbird restricted to the Marañon drainage of northern Peru and extreme southern Ecuador. It has dull green upperparts, light gray underparts, green flecks on the throat, and a white spot behind the eye. Similar to Tumbes Hummingbird, but throat spots are much more conspicuous and range does not extend to the Pacific side of the Andes. Inhabits dry and semi-humid forest and scrub.
Black-cheeked Gnateater
Conopophaga melanops
Small, compact bird with long legs and a short tail. Inhabits the dense understory of humid forests and second growth where it can be very difficult to see. Males are olive-brown above and gray below, with a rufous crown, a black face, and a white throat. Females lack the black face and have buffy-brown body with a white throat and eyebrow resembling Rufous Gnateater, but female Black-cheeked Gnateaters have an all dark bill (not bicolored as in Rufous Gnateater).
Rio Branco Antbird
Cercomacra carbonaria
A slender, long-tailed bird of dense gallery forests and river islands in northern Brazil and extreme southwestern Guyana. Male is mostly black with tail feathers tipped white and with white scalloping on wings. Female is very different: brownish-gray above and buffy below, with a black tail and white throat streaked black. Like other Cercomacra, tends to stay concealed in dense vine tangles in the canopy and midstory, where it clambers slowly about, usually in pairs, searching for insects. Best detected by voice; two-noted song is given in series of 3–5 phrases, with hiccupping effect; similar to song of Gray Antbird but higher-pitched, faster, and less hoarse. Female is unlike any other species in range. Male is darker than Gray and Blackish antbirds, which do not occur in the same habitat and have different voices. Plumage recalls Dot-winged Antwren, but Rio Branco Antbird is considerably larger.
