An Icy Eagle Encounter

The Bald Eagles were brawling on the ice.

At least, that’s what I thought I saw. I had been watching two juveniles for about twenty minutes.  Motionless in the frigid wind howling over Lake Allegan’s ice, the eagles appeared to be scanning for fish.

That was unusual, however. Our eagles typically conduct surveillance from high in the nearby trees. An island—aptly named Eagle Island by Michigan’s Department of Natural Resources—provides a broad view of the surrounding water. But these birds stood next to a narrow gap in the ice.

Winter’s Stoic Eagles

How do birds stay warm in winter?

They huddle. They puff their feathers, tucking head and feet into the fluff. And they shiver.

Our lake, an impoundment formed by damming a river, rarely wears a full blanket of ice. When the region’s smaller lakes freeze, Lake Allegan still provides open-water fishing. So, while eagles are a common sight, I was surprised to see how these two behaved in the frigid, snowy wind.

Their heads and toes remained untucked, and while likely parent and child, they were not in a huddle.
