Black-girdled Barbet
Capito dayi
Stocky bird with a stout bill. Plumage is largely black and white, but the male has a red cap, and both sexes have a red vent. Canopy dweller in humid forests, including the forest edge; often seen at fruiting trees. Accompanies mixed-species flocks. Sings a series of low, hollow “hooo” notes that accelerates towards the end, similar to the songs of some antthrushes.
识别特征
The black-girdled barbet is approximately 18 cm (7.1 in) long and weighs 56 to 74 g (2.0 to 2.6 oz). The adult male's entire crown and nape are scarlet, the sides of the head black, and the chin and throat various shades of brown. Its back is black. Its underparts are white or off-white on the upper breast merging to pale greenish yellow on the belly. Its flanks are black, which extends nearly across the lower breast forming the "girdle". The adult female differs in that its crown and nape are black. The immature is similar to the adult but duller overall.
分类信息
Since its description in 1916, the black-girdled barbet has almost always been recognized as a species. However, it was briefly considered to be a subspecies of black-spotted barbet (Capito niger). DNA data have shown it instead to be sister to five-colored barbet (C. quinticolor).<p>The black-girdled barbet is monotypic. Its specific epithet dayi honors Lee Garnet Day, one of the leaders of the expedition that discovered the bird.

行为
Little is known about the black-girdled barbet's diet other than that it includes both fruit and arthropods. Its foraging behavior has not been described.<p>Specimens of the black-girdled barbet indicate that it primarily breeds between August and November, though February and June are also implicated. It is assumed to nest in a tree cavity like other New World barbets, but its nest and eggs have not been described.<p>The black-girdled barbet's song is "a steadily accelerating series of hollow boo notes" [1]. It has at least two calls, a series of notes "rok rok ock ock" [2] and "a peculiar grating rattle" [3].

Emperor Goose
Anser canagicus
Stocky goose that inhabits rocky coastlines, lagoons, and tidal flats. Striking white head, black throat, and petite pink bill. Blue-gray body with intricate black-and white bars, a white tail, and bright orange legs. Face sometimes stained orangish-brown. Juvenile has a gray head, but still shows white tail. Breeds on marshy tundra and winters in small flocks on coastal waters. Rarely seen outside Alaska.
Buru Friarbird
Philemon moluccensis
A large, entirely gray-brown honeyeater with a patch of dark facial skin and a long, slightly decurved, sharply pointed bill. Juveniles show a yellowish-green wash to wings and underparts. Singles and pairs inhabit forest, forest edge, and open wooded country. Larger than Buru Oriole, with dark facial area composed of bare skin, and longer, more pointed bill. A noisy bird, giving harsh, kingfisher-like “skidup” alarm notes, a repetitive “chuwee-chow,” and “wee-o-wer” calls.
Black-throated Jay
Cyanolyca pumilo
Rather small and elusive jay of humid evergreen and pine-evergreen forest in mountains. Usually travels in pairs or small groups, at times in association with larger and more conspicuous Azure-hooded Jay. Forages at all levels, usually well hidden in dense vegetation. Plumage dark blue overall with black face and throat bordered by narrow whitish eyebrow. Varied calls can draw attention.
