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.
Black-headed Paradise-kingfisher
The Black-headed Paradise-kingfisher is a spectacularly ornate kingfisher with a black head, vivid turquoise-blue upperparts, white underparts, and extraordinarily long white tail streamers. It inhabits lowland and hill rainforests of the Bismarck Archipelago, including New Britain and Manus, in Papua New Guinea. It hunts insects, lizards, and earthworms in the forest understory, often diving to the ground to capture prey.
