Birds don't inhale air because they don't need to breath.
Air Sac
The function of the respiratory system is to provide the body with oxygen. Oxygen enters the body through the respiratory system and is carried in blood throughout the body.

Oxygen comes in from the air into your lungs.
Air is forced into the lungs.
Very few species of bird actually have feathers covering the nares, or external nostrils. Of these, the woodpecker's the one who needs it to filter the air, specifically from wood particles.
Toucans have two holes in their bills, and have internal lungs, which they use to breathe. Some toucans have bills almost as tall as them.
The same way you do, it inhales air into it lungs through its mouth and nose.

When we inhale air from the environment first enters the nasal cavity.Then it enters wind pipe to bronchi to bronchi-oles to alveoli.Alveoli are the terminal units of the lungs.
It starts in the nose/mouth, then the air enters the lungs. It then goes into the bronchi ole into the air sac. It is then transported to the circulatory system to produce waste. There is another way which is that the nose/mouth inhales air then it travels down the trachea into the lungs where the waste is produced it then goes to the bronchi then into the circulatory system.
Air enters the body when you inhale (Breathe in) air enters through the mouth and into the lungs. and then exhale (Breathe out) carbon dioxide (CO2)

It breathes like any mammal does, inhales air through their lungs, into their blood, and to their heart.
