It was a eureka moment for Scott Isringhausen and the 40 people on his eagle-watching tour last Friday.
They had seen only a few birds in their usual spots along the Illinois River, so the group trudged on to the Winfield Ferry, which crosses the Mississippi from Calhoun County.
"We saw over 100 eagles," Isringhausen said. "No exaggeration. In fact, I'm being conservative. It was fabulous.
"Because of the weather, they're congregating in one place (where the water isn't frozen). It's just breathtaking how many you see. We saw 20 in one tree."
Isringhausen recently became urban fishing coordinator for the Illinois Department of Natural Resources after years as site interpreter at Pere Marquette State Park.
He's still going to lead his popular eagle tours, but only on weekdays this year.
The Winfield Ferry is a good eagle-watching spot because it's just below Winfield Lock and Dam No. 25, where the birds can fish in unfrozen, churned-up water.
"The fish come through the lock and dam, and some them are stunned or killed," Isringhausen said. "That's a lot of food for eagles."
American bald eagles start their migration south from Canada and the Great Lakes in November and December, when waterways freeze and impede fishing. They stay a few months in Madison, Jersey and Calhoun counties.
The colder the temperatures up north, the more eagles in the metro-east. This year, Isringhausen is particularly excited.
"I really think when it's all said and done, this will be one of the best eagle seasons in the area," he said.
Winfield is the only ferry operating right now. The Brussels, Kampsville and Golden Eagle ferries are closed.
Another spot where water gets churned up is Melvin Price Locks and Dam in Alton, which is connected to National Great Rivers Museum.
"We went out with a spotting scope (on Dec. 27), and we spotted about 30 eagles in the treeline on Maple Island and Ellis Island," said Rebecca Fink, a U.S. Army Corps of Engineers park ranger who works at the museum.
"Some were adult, and some were juvenile. We definitely have more eagles than we did last year at this time."
OLD CHAIN OF ROCKS BRIDGE
After a one-year hiatus, Eagle Days are back on the Old Chain of Rocks Bridge in Madison on Jan. 18-19, albeit with fewer activities than in its heyday.
Visitors can look through viewing scopes, take photos with a giant eagle nest and see live eagle presentations every 20 minutes from 9 a.m. to 3 p.m. Bundle up and bring binoculars.
The 1-mile-long pedestrian bridge is a good eagle-watching platform because of its proximity to a chain of rocks across the Mississippi that churns up water.
Eagle Days is sponsored by The Missouri Department of Conservation, Illinois Department of Natural Resources and Trailnet. They canceled the 18th annual festival last year because of money problems.
PERE MARQUETTE STATE PARK
Scott Isringhausen will lead Pere Marquette State Park Eagle Days tours Wednesday and Jan. 17, 24, 29 and 31 and Feb. 3, 4, 6, 7, 13, 14, 19, 21 and 26 and March 7.
Groups meet at the park visitor's center at 8:30 a.m. They watch a short video, load into cars, cross the Illinois River on the Brussels Ferry, take an observational drive with stops in Two Rivers Wildlife Refuge, eat lunch in Hardin and return at 3 or 3:30 p.m.
Tours are limited to 50 people. Thirteen can ride in a van with Isringhausen, and the rest follow in vehicles. There is no charge, but reservations are required. For more information, call 618-786-3323.
Last spring's flooding along the Illinois River knocked out camera equipment used to broadcast live eagle-nest footage to the Pere Marquette visitors center.
The nest is in Two Rivers National Wildlife Refuge. Officials doubt they can get the equipment up and running this winter.
"It's such a remote location," said Pam Warford, assistant superintendent. "Some of the (eagle nests seen) on the Internet are a little bit easier to access."
ALTON REGIONAL CONVENTION AND VISITORS BUREAU
