Windows pose a serious threat to avian populations

Many of us have witnessed it: We’re in our home or business and hear a loud smack. It sounds as if somebody tossed something against a window, but we quickly realize that it wasn’t some kid’s errant baseball — it was a hard-flying bird.

The bird sees the sky, woods, park or lawn and an open avenue for flight; a false reflection of safety. Unfortunately, they have no concept of the impenetrable barrier that glass presents and their quick flight ends abruptly on its surface. The impact often results in the death of the bird, and the victims comprise many different species. They are especially at risk during spring and fall migrations.

Northwestern University, in Evanston, Illinois, is working with the local community and experts from American Bird Conservancy, using state-of-the-art solutions to keep birds from dying in collisions with those glass walls and windows.

What prompted Northwestern’s decision to explore a solution to these bird impacts? The university’s location along the shores of Lake Michigan puts it squarely in the path of millions of migrating birds. These historic travel lanes are now filled with buildings and obstacles sporting these glass hazards that increase the mortality rate beyond what nature intends.

Annette Prince, director of Chicago Bird Collision Monitors (, says that 5,000 birds a year are injured or killed by collisions in one square mile of downtown Chicago alone. The birds include 170 species, from wood thrush and many species of warblers to larger birds like bitterns.

“The things we find sometimes are astounding,” Prince said. “We got a painted bunting one year. Even waterfowl can be impacted.”

“We’re taking an active, multitiered approach to bird collisions, looking at new construction, existing structures, and at the daily building-management level,” said Bonnie L. Humphrey, director of design in Northwestern’s facilities division.

Some of the adopted solutions include applying patterned window film to problematic existing windows and choosing glass with patterns visible to birds in some new construction projects.

“Northwestern is setting a powerful example that we’d like to see other universities follow. Ideally, you treat a whole building. If you can’t do that, you can at least treat the most dangerous areas,” Prince said.

The measures put Northwestern in the vanguard of a growing movement among U.S. colleges and universities to implement practical, effective and cost-efficient strategies to reduce bird strikes, which kill up to 1 billion birds a year in the U.S. I like to think that the Big Ten is once again leading the way.

If you would like to reduce the number of birds bouncing off your windows, there are several companies that can help. An internet search will find ABC BirdTape, Window Alert, Feather Friendly, AviProtek, Ornilux and others.

Along the way:

Are you a birder, wildlife watcher or a walking enthusiast? Maybe you’d like to get a chance to explore parts of an Ohio wildlife refuge that is generally off limits to casual visitors. The Hike the Dikes program might be the perfect opportunity for you.

The Hike the Dikes program is free and open to all ages and interest levels, providing opportunities to explore the natural wonders of Magee Marsh Wildlife Area and Ottawa National Wildlife Refuge along Lake Erie. All walks are led by a trained and knowledgeable guide. Participants will learn about local birds, reptiles and amphibians, butterflies and marsh mammals, wetland plants and more.

The programs are held in partnership between the Division of Wildlife; Magee Marsh Wildlife Area, U.S. Fish and Wildlife Service; Ottawa National Wildlife Refuge and Black Swamp Bird Observatory. Hikes take place the second Saturday of each month, April through September.

This year’s dates are April 14, May 12, June 9, July 14, Aug. 11 and Sept. 8. Each walk is hosted by one of the partner agencies.

Hikes begin at 9 a.m. and usually last one to two hours, depending on the weather. April’s hike will meet at the Sportsmen’s Migratory Bird Center at Magee Marsh Wildlife Area, located at 13229 Ohio 2 W, Oak Harbor 43449.

All other hikes will meet at the Ottawa National Wildlife Refuge Visitor’s Center, located at 14000 Ohio 2 W, Oak Harbor 43449.

Anyone who attends three or more Hike the Dike walks will receive a free hiking stick. For more information, call Magee Marsh Wildlife Area at 419-898-0960, ext. 21, or Ottawa National Wildlife Refuge at 419-898-0014.

Some items that could come in handy include binoculars, camera, sketchbook or notebook.
