Essay on Adaptation of Birds

Birds have developed the ability to maintain flight at various altitudes. The focus of this essay was placed specifically on flight at high altitudes. The characteristics of birds which maintain flight at high altitudes were found to be enhanced gaseous exchange efficiency, higher O2 affinity haemoglobin, and increase O2 diffusion to muscle fibers as a result of an increase in capillary-fiber ratio in a high-altitude hypoxic environment. It has also been seen that birds found at high altitudes have larger wingspans thereby reducing the energetic costs of flight in low-density air.
