Andean goose (Chloephaga melanoptera) and Bar-headed goose (Anser indicus) have special adaptations to living at high altitudes. The populations found living at high altitudes have amino acid changes in their haemoglobin genes. The changes in the haemoglobin structure allows these geese to more effectively bind oxygen at lower concentrations (as is the case at high altitudes), which prevents these birds from developing hypoxia.
