:''For the Chinese bird ''Luscinia obscura'', see Blackthroat'' The black-throated robin (''Poecilodryas albonotata'') is a species of bird in the family Petroicidae. It is found on the island of New Guinea in Indonesia and Papua New Guinea. Its natural habitat is subtropical or tropical moist montane forests at 1,150–2,750 metres above sea-level. Described by Gregory Mathews in 1920, the black-throated robin is a member of the Australasian robin family Petroicidae. Its genus name is derived from the Ancient Greek words ''poikilos'' "little" and ''dryas'' "dryad", and the species name ''albonotata'' is derived from the Latin words ''albus'' "white" and ''notata'' "marked". Sibley and Ahlquist's DNA-DNA hybridisation studies placed this group in a Corvida parvorder comprising many tropical and Australian passerines including pardalotes, fairy-wrens, honeyeaters and crows. However, subsequent molecular research (and current consensus) places the robins as a very early offshoot of the Passerida (or "advanced" songbirds) within the songbird lineage. Measuring , the black-throated robin has a grey-black face, throat and upper breast with a grey crown and nape, and a white diagonal mark on the neck. The upperparts are blue-grey, and the underparts grey to white over the abdomen and under the tail coverts. The bill and legs are black, and the eyes are dark brown. The plumage is reminiscent of a cuckoo-shrike but the white neck marking is diagnostic. The black-throated robin is found predominantly in rainforests along the central highlands of New Guinea, from the Bird's Head Peninsula in the west to the Huon Peninsula in the east, at altitudes from . Within the rainforest, it is found singly in the understory or on the ground. It is insectivorous, and hunts by gleaning.〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Black-throated robin」の詳細全文を読む スポンサード リンク
