Red-breasted Mergansers (click to see the larger version)

Red-breasted Mergansers have arrived in force on the southern end of Lake Michigan. Hundreds to thousands of these fish eating ducks have been at Montrose and other Illinois lakefront locations the last few days. Red-breasted Mergansers are one of three common wintering ducks on Lake Michigan, the other two being Common Merganser and Common Goldeneye. Luiz Munoz photographed this swarm of Red-breasted Mergs at Montrose on December 3, 2016.
