About These Birds
Yellow-shafted Flicker
北米全域に広く分布するキツツキ（体長28〜36cm）。褐色の羽毛に黒い斑点、翼の鮮やかな黄色や橙色（亜種により異なる）が特徴的。Colaptes auratus（アリスイ属の北米種）は他のキツツキと異なりアリをなめ取ることが多く、地面での採食も多い。都市公園から農地まで広く生息する。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.
