Birds have lungs like a human does, but they also have 7-9 air sacs. They do not have a diaphragm. The air sacs move the air in and out of the chest. Humans are diaphramic breathers and birds are ribcage breathers -- thier sternum (breastbone) must move or they will suffocate. Instead of alveoli where gases are exchanged in the human, the bird has a different setup called an air capillary which is much more efficient than alveoli.
