Glen Loyd Videos: Rock River fly swarms look like bird murmuration
You have probably seen videos of mumurations where thousands of starlings band together in the air, flying smoothly as one, darting up and down, zigzagging and looping into each other without touching. “We may never be able to fully explain why these birds create such extravagant displays,” says Dr. Paul R. Cabe, professor of biology at Washington & Lee University, who wrote his thesis on starlings.
Safety in large numbers is often cited as one reason. River flies currently hatching and swarming over the Rock River for reproduction also fly in beautiful formations that look like bird mururations. Glen captured their aerial acrobatics in his son's back yard on the River.
