Graphic by John Idzikowski News from the Night Sky Radar and Songbird Migration Most songbirds migrate at night. They travel high overhead while people are asleep on the earth below. Some people watch these amazing seasonal migrations at night using weather radar technology. This spring, Mr. Kevin Kearns of Neenah, Wisconsin will share his observations with us. He watches the internet where special weather maps--designed to detect oncoming storms--also detect migratory birds as they pass overhead. "Soon after sunset, the radar begins to detect disturbances in the air. These are birds that are taking advantage of the more stable air that occurs after sunset," begins Mr. Kearns. Is tonight a good night for migration? What time of night do the songbirds travel? How high do they fly? How many are migrating tonight? With skill, these experts and their high tech tools are beginning to answer such questions. Special thanks to Mr. Kevin Kearns and Mr. John Idzikowski for sharing the view! Get Ready... Then Try it!
