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.
Biak Paradise-kingfisher
The Biak Paradise-kingfisher is a near-threatened, spectacularly plumaged kingfisher endemic to Biak Island in West Papua. It has elongated white tail streamers, turquoise-blue and chestnut plumage, and a bright red bill. It inhabits lowland rainforest and is highly dependent on undisturbed forest for nesting and foraging on earthworms and insects.
