Many people believe that a bird's home and place to sleep is
it's nest, but there is no scientific evidence to support this idea.
Zoologist observing birds found that they don't roost overnight in their
nests, even if a storm is coming. Mallard ducks and swans often tuck their heads
between their wings and bodies and float on the water at night. Cranes, with
their long legs, are fond of sleeping on the ground.
Since they don't
sleep in the nest, why do birds still build nests? Birds usually lay and hatch
eggs in their nests. After the eggs hatch, the nest becomes a place for the
mother bird to care for her chicks. The nest soon becomes crowded as the chicks
grow. After a while, there is no longer room for the mother in the nest. After
the chicks grow into adult birds, the nests are abandoned. In short, there are
nine thousand species of birds on the earth and most of them only use nests for
breeding. They don't sleep in them at night.
