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.
King Penguin
The king penguin is the second-largest penguin species, known for its striking orange-gold head markings. Unlike most penguins, king penguins do not build nests — they incubate their single egg on their feet. Their 14-16 month breeding cycle is the longest of any penguin species.
