The animal known for its ability to fly at high altitudes is the bar-headed goose. This remarkable bird migrates over the Himalayas, reaching altitudes of up to 29,000 feet (8,848 meters), which is similar to the height of Mount Everest. The bar-headed goose has adapted to these extreme conditions with specialized physiological traits, such as a higher concentration of hemoglobin in its blood, allowing it to efficiently utilize oxygen at lower levels. Their incredible migratory journey showcases not only their resilience but also the incredible adaptability of wildlife in challenging environments.
