July 10, 2018 – A Double-crested Cormorant, illuminated by the morning sun, was seen perched on a snag just above the slow but steady flow of the Kankakee river. The Double-crested Cormorant is a goose sized bird that is considered a medium-distance migrant having a winter range from Southern Illinois to the Gulf Coast and from Texas to the Atlantic. They are a seabird that occupy inland lakes and rivers that have a good food source of fish and other aquatic life throughout their range. During the nesting season some populations along the coast are localized and don’t migrate while others head north into the northern parts of United States and Canada with large numbers in the Great Lakes region. The Double-crested Cormorant is federally protected under the Migratory Bird Treaty Act, but large concentrations of the cormorants are having a negative impact on aquaculture. There are also concerns of the effects on other threatened or endangered species. The science continues on the Double-crested Cormorants helping to gain a better understanding of their interactions with fish, humans and other species of birds that will eventually lead to best management practices for all concerned.
