Narrative:

B767-400 flight; reduced power takeoff; at 300 feet aircraft struck large bird. Instantly heard loud noise coming from right engine. Saw right engine vibration indicator at 5.0. We immediately reduced right throttle to decrease vibration and noise; left flaps at 15; climbed to 5000 feet and informed ATC; accomplished the QRH engine failure checklist; did not shut down engine but kept it at idle. We then proceeded to QRH fuel dumping procedure; dumped all fuel from center tank and prepared to land at 355;000 lbs. Which is 5000 pounds over landing weight. Made a normal landing. Shut down right engine after landing and taxied to gate with one engine.
