Kingfisher Quiz – Plunge Diving and Bullet Train Beaks

The common kingfisher hunts from a perch above rivers and ponds. When it spots a fish, it dives headfirst, closing a clear third eyelid and adjusting for the way light bends at the surface.

It carries the fish back to a branch, beats it to stun it and swallows it headfirst. Its bright blue comes not from pigment but from feather structures that scatter light.

Japanese engineer Eiji Nakatsu used the kingfisher's beak as a model for the nose of the Shinkansen 500 Series, cutting the boom when trains left tunnels. Kingfishers nest in riverbank tunnels, and relatives such as the kookaburra hunt on land.
