  Simplest answer is because they have very powerful wings capable of carrying their full body’s weight, and their bodies are shaped in a streamlined way with very light bones that makes them light enough to be carried by air.

  And not all birds fly, some have given up flight in favour of growing bigger (say an ostrich).
