Bald Eagle Migration

Every year between the middle of December until early February the North American Bald Eagle migrates to the Quad Cities area from northern Wisconsin, Minnesota and Canada. During this time you can travel along the river and constantly see these magnificant raptors.

When the river freezes, the best places are near the lock and dams where the water is open. I especially like to hang out just wet of Lock and Dam 15 on the Iowa side. It is here you can see many eagles perched on the trees across the river near arsenal island.
At any time you will see between 1 and several hundred eagles flying over the water. Most of the time a few of them will be flying circular patterns and diving for fish. If you are lucky to see them approach you at a close distance, they will look at you intently as shown by the image below.

It is said that a bald eagle can read a newspaper from 100 yards away. As they glide effortlessly using the wind, they constantly scan the water looking for an unlucky fish. Once they locate their prey, the wings fold back as their feet retract like a landing gear on an aircraft and they twist their body to dive. Just before hitting the water they flare their wings to stop in midair just as their razor sharp talons dip into the water to grab the unsuspecting fish.


Although not all attempts are successful, when you can see them catch one, it is quite rewarding.
