monarch flycatcher : ウィキペディア英語版 | monarch flycatcher
The monarch flycatchers (''Monarchidae'') comprise a family of passerine birds which includes boatbills, shrikebills, paradise flycatchers, and magpie-larks. Monarchids are small insectivorous songbirds with long tails. They inhabit forest or woodland across sub-Saharan Africa, south-east Asia, Australasia and a number of Pacific islands. Only a few species migrate. Many species decorate their cup-shaped nests with lichen. ==Morphology and description== The monarch flycatchers are a diverse family of passerine birds that are generally arboreal (with the exception of the magpie-larks). They are mostly slim birds and possess broad bills. The bills of some species are quite large; the boatbills of the genus ''Machaerirhynchus'' are very broad and flat, and the heavy-set bills of the shrikebills are used to probe dead wood and leaves. The plumage of the family ranges from sombre, like the almost monochrome black monarch, to spectacular, like the golden monarch. The tails are generally long and spectacularly so in the paradise flycatchers in the genus ''Terpsiphone''. Sexual dimorphism in plumage can be subtle, as in the paperbark flycatcher, where the female is identical to the male except for a slight buff on the throat; striking, as in the Chuuk monarch where the male almost entirely white and the female entirely black; or non-existent, as in the Tahiti monarch. In some species, for example the Madagascar paradise flycatcher, the males have two or more colour morphs.
