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.
