how do rainbow lorikeets breath?

Answer 1

Birds breathe using a unique system in which air follows a one-way route through the respiratory system. This system is unlike our lungs, in which the air backtracks where it came from. Their system of respiration (breathing) is very efficient - much more efficient than our system.

Birds have two relatively small lungs (where gas exchange occurs), but the lungs are augmented by bellows-like air sacs (where no gas exchange occurs). These air sacs keep the lungs perpetually inflated (even when the bird is exhaling). Our lungs alternately fill and empty out. The bird's respiratory system takes up 20% of a birds's volume (our respiratory system takes up only 5% of our volume).

In the bird's respiratory system, air first flows through air sacs (located even inside their hollow bones) that direct fresh, oxygenated air into the tube-like lungs (parabronchi, where gas exchange occurs) both when the bird inhales and when it exhales.

This system increases birds' respiratory efficiency and gives them enough oxygen for flight.

Answer 2

If you look above the beak, there are two holes with some fleshy area. that's the nares, they breath through that. :D
