White-winged Scoters on Griggs Reservoir

It’s always exciting when something unexpected is discovered. Since Griggs Reservoir and the park that runs along a portion of it’s eastern shore are located within the city limits of Columbus, our expectations are not always real high when it comes to seeing unusual wildlife. Such was the case during yesterday’s walk along the reservoir.

It was a cold, windy, but sunny day and the even though the temperature was below freezing the ice was mostly off the reservoir due to recent warm weather and heavy rains. The first thing we noticed was the unusually high number of Ring-billed Gulls. Some were in large groups and others scattered about. Some were in the water and other were relaxing on the numerous ice rafts still floating in the reservoir.

It soon became obviouse what was attracting the gulls. Numerous dead, but remarkable “fresh” looking, shad were on the ice, in the water, and along the shore. Recent high water and turbidity, rapid rain induced temperature fluctuations, and lack of oxygen due to the winter’s heavy ice cover may have all led to their demise.

With the reservoir mostly free of ice waterfowl had dispersed from open water areas in the Scioto and Olentangy Rivers. We saw Goldeneyes, Hooded Mergansers, and Ringed Necks. Unfortunately they were all swimming along the opposite shore so no National Geographic quality photos were possible and those taken fell into the category of data acquisition.

But the highlight of our day was the unexpected sighting of six White-winged Scoters.
