A peregrine falcon that has been mostly seen sitting on the ledge of a skyscraper near the intersection of Wacker Drive and Monroe Street has apparently attacked several pedestrians who have presumably gotten too close to the bird's little ones.
For Chuck Valauskas, it was a lesson learned the hard way.
"I felt this clunk against my head, like a 16-inch softball. I looked up and I saw this bird swooping away and it went up to the ledges on this building," Valauskas told NBC Chicago.
Last Thursday, Chuck Valauskas was walking here along the river near his office when the bird came after him.
The birds drew blood on Valauskas, and he sought medical treatment the following day, when he received a tetanus shot.
Those working in the nearby building were warned of the bird's presence, with apparently several other individuals being attacked by the falcon.
Several warning signs have now been posted near where the bird attacks have occurred, making the large amount of pedestrians walking near the falcon's territory each day aware of its presence.
