Is There Any Bird That Shines?

In the forests of Africa, there are orange-coloured birds that shine at night. Local people love the birds and call them glowbirds. Many people raise the birds m cages and carry them as lamps to light their way at night. How can the birds shine? These birds have feathers only on their heads and wings, while other parts of the body grow a layer of orange-coloured hard shell. Inside the shell are luminous cells. At night light comes from the hard shell and shines like a small lamp.
