Anatomy, variation, and asymmetry of the bronchial tree in the African grey parrot (Psittacus erithacus)

The avian respiratory system includes an immobilized, nearly volume-constant, gas-exchanging lung connected to a set of air sacs that fill the body cavity. These micro-computed tomography (µCT) scans of deceased African grey parrots (Psittacus erithacus) were used to analyse anatomical variation in the the gas-exchanging lung by taking select metrics and by generating 3D surface models of airways. The data include select portions of eleven axial µCT image series taken every 94.19–97.23 µm and one axial µCT series taken every 41.08 µm.
