Canvasback Ducks

A mixed flock of mostly Canvasback ducks feeding and socializing on a flooded access road leading into the Kaskaskia bottoms in Southern Illinois this past week.

February 27, 2020 – The male Canvasback duck has a rich chestnut colored head and neck, black chest and tail area, with a bright white body and wings. These large ducks have beautiful red eyes that when illuminated by the sun can penetrate the thoughts of the human observer laying waste to any earthly woes, at least temporarily. Those unique eyes of this big diving duck absolutely contribute to making this bird a strikingly handsome fellow. The female, on the the other hand, is less colorful and has a pale-brown overall plumage that is most certainly required for a nesting female duck. Her camouflaged coloring is mandatory to helping keep her and her nest hidden from predators. But even without the strong contrasted colors she is still quite beautiful and is easily identified as a Canvasback. The female has the same sloping forehead and large black pointed bill but she does not have those amazing red eyes like the male. Her eyes are very dark in color, perhaps part of her specialized trait of survival. Throughout the Mississippi Flyway these fast flying migrating ducks, that are considered diving ducks, congregate in flocks from ten to many thousands. During the winter in the southern half of the United States including most of Illinois from southern Lake Michigan south where they can find open water and food they can be found in their winter flocks. In the southern winter marshes, lakes, rivers, and flooded fields the Canvasbacks feed together in an amazing display. The ducks come together over the area to forage and begin their search for tubers and invertebrates by diving repeatedly in a rolling head-first fashion that is somewhat mesmerizing when there are a large number of birds involved. The Canvasback ducks migrate north and west in the spring and nest in the prairie pothole region, those glacial wetlands of North America and Canada. They also nest north in the wetlands and marsh areas from the Great plains to Alaska.

Winter Waterfowl

February 5, 2019 – The cold weather has brought the winter waterfowl to the open icy waters of the Kankakee river. Common Goldeneye, Common Mergansers, Redheads, Canvasback ducks and more can be seen feeding and resting below the dam near Jeffers park in Kankakee. Jed Hertz spotted a White-winged Scoter this past Saturday, the Scoter is a rare visitor that is usually seen during the winter months on the Great lakes and the coastal areas of the United States and Canada. In one photo a male Canvasback duck is swimming with two male Redheads, look close, they are very similar species. The other photo shows a male Canvasback and a female that appears to be sleeping, don’t let her fool you, she is quite alert as she floats along the icy shore of the Kankakee river.

The Common Goldeneye ducks fly up river towards the dam and land near the Washington Street bridge where they begin diving for crayfish as the current takes them back down river, a process that is repeated over-and-over again. The Common Mergansers do the same thing, catching small catfish, bass and shad. Ring-billed and Herring gulls swoop in to steal the prey from the ducks as soon as they surface with their catch. Mallard ducks, Greater Scaup, Lesser Scaup and the American Black duck can also be seen down river from the dam.
