Mirgration

In some cases severe weather will trigger large amounts of ducks to migrate at one time. This would be called a grand passage. Most ducks fly at speeds of between 40 and 60 mph with most averaging around 50 mph. While migrating most ducks hit altitudes between 200 and 4,000 feet but can go much higher. Birds use different visual and nonvisual cues to help them navigate. They use different things such as the sun, polarized light, the stars, and landmarks.
