Differences between avian and mammalian respiration Respiration in birds is much different than in mammals. z Birds have a larynx, but it is not used to make sounds. Instead, an organ termed the syrinx serves as the voice box.. z Birds have lungs, but they also have air sacs. Birds do not have a diaphragm; instead, air is moved in and out of the respiratory system through pressure changes in the air sacs. Muscles in the chest cause the sternum to be pushed outward. This creates a negative pressure in the air sacs, causing air to enter the respiratory system.
