Suddendly, all the birds break free and begin flying inside the airplane.
Does the plane become 2 tons lighter?

No the plane does not become 2 tons lighter. The downforce of the air due to the flapping of the birds wing to stay aloft equals the birds body weight. This compensates for the birds leaving their seat. Do I win?
