The bird apparently struck the nose. Maintenance crews found no significant damage and gave the Airbus 320 the OK to fly.
The flight arrived at O'Hare about 90 minutes behind schedule.
"You always think of the one in New York and the Hudson River, but ours wasn't nearly that dramatic," said Dan Costello, passenger.
"There was some concern, a little apprehension. It's good," said Ron Shrok, passenger.
"It was pretty anti-climactic. It was pretty uneventful. There wasn't anything that was very scary after the first announcement that there had been a bird strike," said Joseph Mills, passenger.
Because the Sacramento airport sits near a migratory bird path, it sees a high number of bird strikes.
