About These Birds

Bay Woodpecker

アカエリキツツキは東ヒマラヤからインドシナ南東部にかけての山地林に生息する大型の赤褐色キツツキで、縞状の赤褐色の背・雄に赤い頭部模様・力強いノミ状の嘴を持つ。密な亜熱帯・山地林で樹皮をはがして昆虫・幼虫・アリを採食する。

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.
