Bar-headed Goose

The world's highest flying bird is an Asian goose that can fly up and over the Himalaya in only about eight hours. the researchers discovered that instead of flying in the early afternoon, when heat from the earth can create 12-mile-per-hour updrafts, bar-headed geese consistently fly at night or during early-morning hours, when there is actually a slight downdraft.

Another hypothesis about why the geese choose to fly over rather than around the Himalaya is that the birds have been doing so for millions of years—long before the mountains reached their current heights.
