The black-capped kingfisher (''Halcyon pileata'') is a tree kingfisher which is widely distributed in tropical Asia from India east to China, Korea and Southeast Asia. This most northerly of the Halcyonidae is resident over much of its range, but northern populations are migratory and they wintering south of their range to Sri Lanka, Thailand, Borneo and Java. It is distinctive in having a black cap that contrasts with the whitish throat, purple blue wings and the coral red bill. The species is mainly found in coastal and mangrove habitats but can sometimes be found far inland. == Description == This kingfisher is about long. The adult has a purple-blue wings and back, black head and shoulders, white neck collar and throat, and rufous underparts. The large bill and legs are bright red. In flight, large white patches or "mirrors" at the base of the primaries are visible on the blue and black wings. Sexes are similar, but juveniles are a duller version of the adult and show streaks on the throat. The call of this kingfisher is a cackling ''ki-ki-ki-ki-ki''. Usually seen on coastal waters and especially in mangroves, it is easily disturbed, but perches conspicuously and dives to catch fish but also feeds on large insects. The flight of the black-capped kingfisher is rapid and direct, the short rounded wings whirring. The breeding season is in summer. The nest is a tunnel in an earth bank. A single clutch of 4-5 round white eggs is typical.〔 A subspecies ''palawanensis'' has been described but the species is considered to be monotypic with no clear plumage differences across their range.〔 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-capped kingfisher」の詳細全文を読む スポンサード リンク
