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.
Common Ostrich
The common ostrich is the world's largest living bird, standing up to 2.7 meters tall and weighing up to 145 kg. Despite being flightless, it is the fastest bird on land, sprinting at speeds up to 70 km/h. Ostrich eggs are the largest of any living bird, weighing about 1.4 kg each.
