Can flying birds swim

Can All Birds Fly ???Certain elements in are life are merely taken as granted. When I say this line, what I actually mean is, for example, if a small child asks us the question, " What is a bird? ", our general answer to that would be, "Anything that flies is a bird."By actually giving that answer, you have just given the most generic obvious answer to that question.

But, in reality, all birds do not fly. The Ostrich and the penguins are birds, but they do not fly, rather they can't fly. So, the answer to the question, "Can all birds fly?", the answer "Yes" is obviously a False statement.
