Believe it or be stupid, birbs breath through MOUTHS. feathers keep birds warm.
Yes , birds breathe through lungs as they live on land.
No. Technically, birds don't have a nose. They have a beak. Their beak has nostrils through which they breathe.
Birds breathe with lungs. Only fish breathe with gills.
Lungs? They breathe through their nostrils and the air goes into the lungs where the oxygen goes into the blood stream. -Birds have lungs and air sacs, which direct air through the lungs in a one-way...
Kind of. I think the air sacs help them to breathe and keep them from over heating/having a heart attack. (They do breathe through lungs)
