About These Birds

Great Spotted Woodpecker

ヨーロッパからアジアにかけての森林に広く分布するキツツキ（体長22〜23cm）。黒・白の羽毛に雄の赤い後頭部と下腹部が特徴。Dendrocopos major（アカゲラ）は木に穴を掘って巣を作り、木の幹を激しくドラミングする。日本でも山地の広葉樹林や針葉樹林に生息し、秋冬には公園でも見られる。Picidae科。

Downy Woodpecker

The downy woodpecker is the smallest and most widespread woodpecker in North America. Its small size allows it to forage on thin branches and weed stems that larger woodpeckers cannot access. Downies often join mixed-species flocks in winter, benefiting from the extra vigilance of multiple species watching for predators.
