January 7, 2021 – Each winter Bald eagles move south into Illinois in large numbers as hundreds can be seen perched in the tall Sycamores and Cottonwoods along the Mississippi river, near the locks and dams, where the churning ice free waters are abundant with fish that are easy pickings for the eagles. From December through March these wintering eagles are not hard to find, where there is fish there are eagles. There are festivals and eagle watches at many cities and parks that have rivers and lakes throughout the state. These celebrations give people the opportunity to learn about eagles from experts while observing these great birds of prey in the wild. Some of the eagle watching events may understandably be postponed or canceled this year due to the coronavirus but eagles can still be observed from the safety of your vehicle from the parking areas around lakes and along rivers. Recent estimates of wintering eagles in Illinois is over 3000 birds. The U.S. Fish &Wildlife Service estimates in 2004 there were 100 nesting pairs in Illinois, a number that has likely increased. The American Bald eagle is becoming more of a common sight here in Illinois in recent years. The Bald eagle recovery is the absolute result of the hard work of dedicated biologists, environmentalists, and citizen scientists. A number of state and federal laws enacted over the years, beginning with federal protection specifically for the eagle, was passed by Congress in 1940. Shortly after the Bald Eagle Protection Act became law the Golden eagle was added, and the name was changed to the Bald and Golden Eagle Protection Act. In 1972 the synthetic pesticides DDT that was being widely used and released into the environment without the proper understanding of the long and short term affects on humans and wildlife was banned in the United States. Rachel Carson’s celebrated but controversial book published in 1962, Silent Spring, raised public awareness with an urgent message of the danger and damage being done to the environment with the use of the pesticide DDT. It was found that DDT does not break down easily and builds up in the tissues of animals causing problems up the food chain. DDT was believed to have a profound consequence on Bald eagle reproduction causing their eggs to be brittle and easily damaged while being incubated. Eagle populations began to drop dramatically until the ban on DDT. Today eagles can be seen year around on the Kankakee and Iroquois rivers and with a little patience and some binoculars you are likely to be rewarded with something memorable.
