If you've ever watched a common loon take flight, you've probably noticed it doesn't simply lift off the water. Instead, it runs across the lake, flapping its wings while building speed. Depending on the wind and water conditions, a loon may need 100 to 600 feet of open water before it can become airborne.
Loons have dense bodies and relatively small wings, making takeoff more challenging than it is for many other birds. That's why they are most often found on larger lakes with enough room for a long takeoff run.
Watching a loon race across the water before finally lifting into the air is one of the most unforgettable sights in Minnesota. It also explains why protecting large, healthy lakes is so important for loon habitat.
