Detailed explanation-1: -All birds fly. ⇒ False. While birds are known for their ability to fly, there are many that do not fly such as penguins (who swim), ostriches, emus, and kiwis.
Detailed explanation-2: -Not all birds can fly. Birds like penguins, ostriches and emu cannot fly due to their heavy bodies.
Detailed explanation-3: -Most birds fly. They are only incapable of flight during short periods while they molt (naturally shed their old feathers for new ones). There are, however, several birds that do not fly, including the African ostrich, the South American rhea, and the emu, kiwi, and cassowary of Australia.
Detailed explanation-4: -Birds fly by flapping their wings, steering mainly with their tails. Compared to the parts of an airplane, a bird’s wing acts as both wing and propeller.
Detailed explanation-5: -Birds have hollow bones that are very light and strong. Their feathers are light and the shape of their wings is perfect for catching the air. Their lungs are great at getting oxygen and very efficient, so they can fly for very long distances without getting tired.
