When flying, birds adjust their breathing rate so that they take more breaths per minute instead of taking in more air. Instead they inhale and exhale using special muscles that expand or contract the entire body cavity and air sacs.The way they breathe allows migrating birds to fly in the thin air thousands of feet above the earth, a feat we can only marvel at from below.

But just how does a birds respiratory system work? The inhaled air reaches a dead end when it enters our lungs. Lungs serve the vital purpose of bringing oxygen into the bloodstream to meet the birds metabolic needs, and removing waste carbon dioxide from the birds body via a gaseous exchange process. This is not the case for us as not all of the air in our lungs is expelled when we exhale; it sits in our lungs and mixes with the new air.
