Thanks to the Wright brothers, Orville and Wilbur, today we can take a plane and go from one country to another. They invented successfully the first airplane, which was piloted by Orville in 1903. But with all respect that these two American inventors really deserved, I think we should give credits to birds first, since it was Wilbur’s interest in the observation of birds what made possible the Wright brothers’ flying machine. Human beings, therefore, have always associated the idea of flying with birds, and now the question is can really all birds fly?
The answer is no. The ostrich, kiwi, emu and penguin are examples of birds that cannot see the ground from the air.
