The Cracticinae, bellmagpies and allies, gathers together 12 species of mostly crow-like birds native to Australasia and nearby areas. Historically, the cracticines – currawongs, Australian magpie and butcherbirds – were seen as a separate family Cracticidae. With their 1985 DNA study, Sibley and Ahlquist recognised the close relationship between the woodswallows and the butcherbirds in 1985, and placed them in a Cracticini clade, now the family Artamidae. The two species of peltops were once placed with the monarch flycatchers but are now placed here. Today, most taxonomists consider them once again to be separate families. The cracticines have large, straight bills and mostly black, white or grey plumage. All are omnivorous to some degree: the butcherbirds mostly eat meat; Australian magpies usually forage through short grass looking for worms and other small creatures; and currawongs are true omnivores, taking fruit, grain, meat, insects, eggs and nestlings. The female constructs bulky nests from sticks, and both parents help incubate the eggs and raise the young thereafter. The cracticines, despite their fairly plain, utilitarian appearance, are highly intelligent and have extraordinarily beautiful songs of great subtlety. Particularly noteworthy are the pied butcherbird, the pied currawong and the Australian magpie. ==Species of Cracticinae== Three genera are recognised. The Australian Magpie has been classified in its own genus, however a 2013 molecular study has shown it to be the sister taxon to the black butcherbird (''C. quoyi''). * Subfamily Cracticinae: * * Genus ''Peltops'' * * * Mountain peltops, ''Peltops montanus'' * * * Lowland peltops, ''Peltops blainvillii'' * * Genus ''Cracticus'' * * * Australian magpie, ''Cracticus tibicen'' * * * Black butcherbird, ''Cracticus quoyi'' * * * Hooded butcherbird, ''Cracticus cassicus'' * * * Tagula butcherbird, ''Cracticus louisiadensis'' * * * Pied butcherbird, ''Cracticus nigrogularis'' * * * Black-backed butcherbird, ''Cracticus mentalis'' * * * Grey butcherbird, ''Cracticus torquatus'' * * Genus ''Strepera'' * * * Pied currawong, ''Strepera graculina'' * * * Black currawong, ''Strepera fuliginosa'' * * * Grey currawong, ''Strepera versicolor'' A fossil right scapula (MNZ S41061) found at the Manuherikia River in Otago, New Zealand and dating from the Early to Middle Miocene (Awamoan to Lillburnian, 19-16 million years ago) represents a member of the Cracticinae. ''Kurrartapu johnnguyeni'' was described from a proximal tarsometatarsus recovered from the Riversleigh site in Queensland. It is early Miocene in age and is closer to ''Strepera/Cracticus'' than to ''Peltops''. The bird was likely similar in size to the extant black butcherbird. 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「Cracticinae」の詳細全文を読む スポンサード リンク
