Bizarre incident at Chicago's O'Hare International Airport: a large green bird, apparently a type of parrot, entered Terminal 5 and began rampaging near the "Air France" stand • The bird sat on the heads of passengers, landed on the luggage and even tried to bite some of them • An employee recorded the chaos that lasted for hours: "Every time they tried to approach it, it chose to attack instead of fleeing" • Watch the documentation
