About These Birds
Common Kingfisher
普通翠鸟（Alcedo atthis）— 广泛分布于欧亚大陆和非洲的亮蓝橙色鸟类。栖息于溪流和池塘旁，以鱼类为食。
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.
