About 5 million birds are expected to migrate over Chicago via the Mississippi Flyway, a migratory route between Canada and South America.

But not all birds make the journey: Some get injured or die along the way.

How Chicagoans Can Make Birds’ Trips Easier

Turn off your lights after 11 p.m. if you live in a tall or short building along the lakefront, which are often along flight paths. Some birds continuously circle the buildings and die from exhaustion or collision.

Call the Chicago Bird Collision Monitors if you find a dead or injured bird at 773-988-1867.
