Why do birds have wings?
Interesting theory......I would say that birds have wings mainly
as an aid to almost evrything they do. Carnivorous birds need their
wings to swoop down on smaller birds. All birds( that have wings
and are capable of flying) use their wings to evade predators and
humans. They use them to hunt, to migrate, to collect materials for
their nests....many things would not be available to brids if they
did not have wings, and most of those things neccesary, hence the
answer. They just need them.
