About These Birds
Common Kingfisher
The common kingfisher is a dazzling jewel of waterways, its iridescent blue plumage caused by light refraction in the feather structure rather than pigment. These birds inspired the design of the Shinkansen bullet train in Japan — the shape of their bill was copied to reduce sonic booms when trains exit tunnels.
Japanese White-eye
O olho-branco-japonês é uma pequena ave verde-oliva com anel ocular branco característico, muito popular como canário de gaiola no Japão e amplamente distribuído na Ásia.
