Birds typically fly at altitudes ranging from a few hundred feet to several thousand feet, depending on the species and environmental conditions. Migratory birds, such as the bar-headed goose, have been recorded flying at altitudes over 29,000 feet in the Himalayas. Most common birds, however, generally fly below 10,000 feet. Factors like weather, food availability, and predators influence their flight heights.
