Narrative:
Encountered a seagull strike in left engine. Vibration noticed immediately after 120kts with buzzing sound from engine. Takeoff continued as no other abnormal engine indications. Capt stated 'continue' at 140 kts. Rotated 145 kts. Normal climb out but noticeable vibration and noise. After 2000 feet checked engine ECAM and #1 N1 vibration showed 9.1. All other engine indications normal. First officer stated he saw a bird on left side and believed we hit it. Captain did not see bird. Leveled off at 5000 feet and vibrations subsided with power reduction. Crew agreed a return to land was prudent. Notified ATC; fas; and passengers. Arrival uneventful. Landing flawless by first officer. Mx inspection revealed damage to several fan blades but no apparent core damage. Feather samples taken. Crew re-assigned for next day duty.
