About These Birds
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.
Black-backed Woodpecker
カナダの焼けた北方林（ボレアル林）に生息する中型のキツツキ（体長21〜24cm）。黒い体に雄の黄色い頭頂部と白い腹の縦縞が特徴。Picoides arcticus（クロキツツキ）は山火事後の焼けた木に生息するキクイムシ類を好み、山火事林の重要な「クリーナー」として機能する。Picidae科。
