Last evening there were over 200 Bald Eagles roosting in the normal migration roost site near the Barn Restaurant north of Prairie du Chien on Cty Rd K. This roost is in the tree line west of the dry docked tow boat south of the restaurant. Very little open water was present for feeding activity. The small spring and open water at the Winneshiek Marina had 12 White Pelicans that were feeding on the few dead shad seen floating at that location. With the expected rise in the Mississippi River water level, because of rain and snow melt, open water should be present around the edges of Gremore Lake. The water level was at 9.5 feet Wed. This morning it is at 11 feet and is expected to go to 17 feet by Tues or Wed. Water goes over the Ambro Road on the north side of Gremore Lake at 13.4 feet. With that amount and volume of water river ice will be moved, or at least raised. More open water where eagles can feed on dead shad will be present. Other sloughs in and around Prairie du Chien are starting to open as well. If the eagles and pelicans move to Gremore Lake as they have in the past the best location to see the birds is from the riverside parking lot of the Crooked Oar Bar and Restaurant. In the past 3 years over 500 eagles were seen on and near Gremore Lake during the migration stop over they make during mid-March.
Popular Eagle Viewing Areas
Currently Eagle viewing is dictated by the weather. With heavy snow cover and cold temperatures the birds will move inland to small streams with open water to feed for fish. Or they will watch for a farmer that is spreading agricultural carion on snow covered fields.
As the weather warms and snow and ice melts additional areas of the Mississippi and Wisconsin Rivers will open. This open water will provide bald eagles areas for catching their favorite food source, fish. In the Prairie du Chien area this open water will include areas along the river front and along St. Feriole Slough south to the Campion Boat Landing. Check open water areas near the Regional Tourism Center and at the Blackhawk Ave and Washington St. bridges. A scope works from these locations. Be sure to stay in your car, as a car is the best bird blind you can have at these locations. The best views of eagle nests occur north of Prairie du Chien. North of the cemetery on Main Street/County Road K there is a nest on the west side of the highway. This nest can be seen by stopping near the no passing zone sign and looking west. The nest is in a large cottonwood tree in the second tree line. Since early January a pair of eagles have been visiting this nest.
Three nests are located off Ambro Road. When County Road K turns to the right, just before the railroad tracks, turn onto Ambro Road. Follow this road to the left into the Ambro Slough area.One nest is located on the Gremore Lake side, east of Ambro Road, just north of the Wisconsin DNR boat landing.This nest is hard to see once the leaves are on the trees.When there are no leaves you can see the nest by stopping on the road and searching the trees along the edge of the lake just north of the landing. By parking on the boat ramp at the Ambro landing you can see a nest in the far tree line straight west of the landing.Just 100 yards south of the Ambro boat landing and on the west side of slough there is another nest in a large cottonwood tree. This nest is easily seen by simply stopping on the road and looking between the cabins into the first tree line.This is a huge nest and has been at that location for many years.
Lock and Dam 9, 11 miles north of Prairie du Chien, is also a good location to observed eagles feeding or sitting in trees along the river. Go to the U.S. Army Corps of Engineers lock area or the Gordon's Bay Boat Landing south of the dam for the best viewing. Eagles can also be found feeding on agricultural carrion in fields along U.S. Highway 18 east of Prairie du Chien, between Patch Grove and Mount Hope. North of Prairie du Chien on State Hwy 27 near County Road N watch for eagles feeding on commercial fish waste and agricultural carion in adjacent fields.
There are 5 active eagle nests in the Prairie du Chien area that are easily viewed. The pair of eagles using any of these nests is busy carrying branches and other nesting material to the nest in preparation for the upcoming nesting activity. Egg laying will occur in late February or early March.
The Mississippi River valley is an ideal wintering habitat for the bald eagle. There is food, shelter, and a good source of lifting winds in this area. The bald eagle prefers fish and the river has an abundance of species for the eagle to catch or scavenge. Eagles will also go inland where food sources are available. Eagles need deep valleys to roost in at night for protection from wind and cold.
During the day they use perching trees near open water feeding areas for resting and searching for food. Large riverbank cottonwood and oak trees are ideal for this perch. Eagles spend much of their time soaring over the river looking for food or moving from one area to another. As the cold air of the morning warms it lifts. The greatest lifting action occurs along the river bluffs. Eagles take advantage of this lifting action and can be seen soaring along the bluffs for hours utilizing this free wind. As long as there is open water on the river there will be eagles in the area.
Prairie du Chien Viewing Areas
A good spot for eagle viewing is between the Blackhawk Avenue and Washington Street bridges in Prairie du Chien. A large artesian well provides open water. Eagles will perch in trees along the slough. Check the trees along the Mississippi River shore near and across from Lawler Park on St. Feriole Island is another location of eagle activity. The park is west and north of the Blackhawk Avenue bridge. A mounted bird scope for viewing is available (located in back of building) at the Wisconsin Welcome Center/Prairie du Chien Area Chamber of Commerce building, 211 S. Main. Enroute to Prairie du Chien watch for eagles soaring or perching in trees in open field areas looking for food.
Tips For Viewing Eagles
You can spend the day or several days viewing eagles. You will need appropriate clothing and binoculars. A spotting scope is nice too. Eagle watching begins in the morning about an hour after sunrise. The birds are most active from then until about 3:00PM, feeding in open water areas. Birds can be seen soaring, perching in riverside trees, and sitting on the ice. By late afternoon the birds will be heading for the roost and will not be active unless you are on a flight path to the roost.
The best places to see eagles in the area include the Gordon's Bay boat landing and Lock and Dam #9, 10 miles north of Prairie du Chien. The boat landing is cleared of snow so eagle watchers can simply park near the ramp facing slightly upstream. Watch for eagles in the big cottonwoods along the Wisconsin shoreline, across the river in trees along the Iowa shoreline, and soaring overhead or over the open water caused by flowing water from the dam. Staying in your vehicle will provide you the best viewing as soaring eagles have been known to come very close to the boat landing with their feeding activity. Eagles will be seen flying and perched in trees along the river as you travel to and from this area from Prairie du Chien.
