''Dryocopus'' is a genus of large powerful woodpeckers, typically 35–45 cm in length. It has representatives in North and South America, Europe, and Asia; some South American species are endangered. It was believed to be closely related to the American genus ''Campephilus'', but it is part of an entirely different lineage of woodpeckers altogether (Benz ''et al.'', 2006) Their breeding habitat is forested areas with large trees, where they nest in a large cavity in a dead tree or a dead part of a tree. They may excavate a new hole each year, creating habitat for other large cavity nesting birds. They are non-migratory permanent residents. They are mainly black in plumage with red on the crown of the head, often as a crest. Most species also have some white areas of plumage, especially on the head, and some have additional red facial markings. The male, female and juvenile plumages of each species usually differ, often in the extent of red on the crown and elsewhere on the head. The flight is strong and direct, and the calls are typically loud wild laughs. The drumming of these large birds can be heard from a great distance. ''Dryocopus'' woodpeckers chip out large holes with their strong bills while searching out insects, especially beetle larvae in trees. They will also take fruits, berries, and nuts. The name ''Dryocopus'' come from the Greek ''drus'', an oak tree and ''kopos'', a cutter. ==Species== * Helmeted woodpecker, ''Dryocopus galeatus'' * Lineated woodpecker, ''Dryocopus lineatus'' * Pileated woodpecker, ''Dryocopus pileatus'' * Black-bodied woodpecker, ''Dryocopus schulzi'' * White-bellied woodpecker, ''Dryocopus javensis'' * Andaman woodpecker, ''Dryocopus hodgei'' * Black woodpecker, ''Dryocopus martius'' 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「Dryocopus」の詳細全文を読む スポンサード リンク
