Mergansers are a common sight–pun intended– on Lake Allegan.
Common Mergansers, or Mergus merganser in ornithology-speak, are social creatures that flock in groups up to 75 individuals. I usually see about half that number, most often in late winter and spring.
These small diving ducks seem to prefer the main channel of our river-turned-lake. In winter, the water beneath our home will freeze. But the main channel’s deeper, swifter water generally does not. So, as the lake began to thaw after the recent polar vortex, I was doubly surprised to see mergansers close to our shore. Not only were they diving for prey in very shallow water, but they were also fishing beneath the ice.
Picture whack-a-mole without the whacking.
