About These Birds
Bismarck Kingfisher
The Bismarck Kingfisher is a vulnerable, small forest kingfisher endemic to the Bismarck Archipelago in Papua New Guinea. It has richly colored rufous and blue plumage typical of dwarf kingfishers. It inhabits the dark forest floor and undergrowth, hunting insects, small lizards, and other small vertebrates.
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.
