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。
Japanese White-eye
The Japanese white-eye is a familiar garden bird across East Asia, beloved in Japan where it is called mejiro. These sociable birds form flocks outside the breeding season and are important pollinators of plum and cherry blossoms. Unfortunately, introduced populations in Hawaii have become invasive, competing with native honeycreepers.
