Eagle Valley, Glen Haven, WI


Eagle Valley is a 1450-acre preserve along the Mississippi River privately owned and managed by Kohler Co. and Kohler Trust for Preservation. Its wooded bluffs, prairie, and river frontage are home to several nesting pairs of Bald Eagles; 87 other bird species have been documented as confirmed or probable breeders on the property. The rich and diverse habitats are also home to dozens of mammals from White-tailed Deer to Masked Shrews, various amphibians and reptiles, including Timber Rattlesnakes, Snapping Turtles, and many other species. In addition to providing an important stopover for birds migrating along the Mississippi, Eagle Valley provides a winter home for hundreds of Bald Eagles, many of them from Canada. Deep, fast-flowing stretches of the river remain open even during the coldest winter weather, providing the eagles and many other animals with a rich source of food and water during that cold, lean season.

Eagle Valley staff have been actively researching raptor ecology since 1989. Projects include raptor migration counts, studies of Bald Eagle winter night-roost dynamics, and eagle satellite tracking. Through these efforts, a great deal has been learned and shared about the eagles that overwinter here and the ecosystem that supports them.

Over the past quarter century, there has been a dramatic return of eagles and nests to the river below. Through a solar-powered wireless system that includes a pan/tilt/zoom camera, a small solar panel (mounted well above the reach of spring floodwater), and two wireless relays – one to pass the signal from the nest to the top of the bluffs, and another to pass the signal from the bluff tops back to the research station at the valley’s head – the nest and eagle activity are available to a wide audience.

The nest we are watching is located just west of Eagle Valley on the Upper Mississippi National Wildlife and Fish Refuge in southwestern Wisconsin. The eagles at this nest have been fledging young since approximately 2007. The Eagle Valley nest camera is a joint venture between Kohler Trust for Preservation, Raptor Resource Project, Kohler Co., and the U.S. Fish and Wildlife Service. Personnel from all partnering organizations participated in planning and execution of the nest camera installation.

We hope you enjoy it!
