Why do bar headed geese migrate?

Bar-headed geese migrate primarily to find suitable breeding grounds and to access better food resources. They travel from their wintering habitats in South Asia to their breeding areas in Central Asia, often flying at extremely high altitudes across the Himalayas to avoid predators and harsh weather. This migration is crucial for their reproductive success, as it allows them to take advantage of seasonal changes in habitat availability. Additionally, their high-altitude migration helps them avoid competition and find abundant food sources during the breeding season.
