Narrative:

Upon the initiation of the takeoff roll; all engine indications appeared normal. Shortly after aircraft rotation; we saw a seagull pass in close proximity on the right side of the aircraft. After gear retraction; we noticed a vibration throughout the aircraft along with a corresponding N1 fan vibration indication of about 3.3 (yellow range) on the #2 engine. The N1 fan vibration abnormal checklist procedure was accomplished which led to the in-flight shutdown of the #2 engine. Then the appropriate checklist tasks were accomplished and ATC; the flight attendant; dispatch; and the passenger were notified of our situation. An emergency was declared with ATC. We returned for a landing at our departure airport; the nearest suitable airport. The approach and landing were uneventful. We taxied to the gate; and the passenger deplaned into the jetway. During the postflt walkaround inspection; 6 fan blades were visibly damaged on the #2 engine along with bird debris. Supplemental information from acn 698977: we called ready for takeoff at taxiway X and tower notified us that some gulls were now on the runway near the centerline abeam the aforementioned taxiway. We were also cleared for takeoff. We accepted the takeoff clearance and began our roll. Moments before rotation we saw some gulls about the runway centerline. All but 1 quickly flew away. At rotation speed I called 'rotate;' and the captain began to rotate the aircraft. At the same time; a gull flew past the r-hand cockpit windows.

Narrative: UPON THE INITIATION OF THE TKOF ROLL; ALL ENG INDICATIONS APPEARED NORMAL. SHORTLY AFTER ACFT ROTATION; WE SAW A SEAGULL PASS IN CLOSE PROX ON THE R SIDE OF THE ACFT. AFTER GEAR RETRACTION; WE NOTICED A VIBRATION THROUGHOUT THE ACFT ALONG WITH A CORRESPONDING N1 FAN VIBRATION INDICATION OF ABOUT 3.3 (YELLOW RANGE) ON THE #2 ENG. THE N1 FAN VIBRATION ABNORMAL CHKLIST PROC WAS ACCOMPLISHED WHICH LED TO THE INFLT SHUTDOWN OF THE #2 ENG.

DURING THE POSTFLT WALKAROUND INSPECTION; 6 FAN BLADES WERE VISIBLY DAMAGED ON THE #2 ENG ALONG WITH BIRD DEBRIS. SUPPLEMENTAL INFO FROM ACN 698977: WE CALLED READY FOR TKOF AT TXWY X AND TWR NOTIFIED US THAT SOME GULLS WERE NOW ON THE RWY NEAR THE CTRLINE ABEAM THE AFOREMENTIONED TXWY. WE WERE ALSO CLRED FOR TKOF. WE ACCEPTED THE TKOF CLRNC AND BEGAN OUR ROLL. MOMENTS BEFORE ROTATION WE SAW SOME GULLS ABOUT THE RWY CTRLINE. ALL BUT 1 QUICKLY FLEW AWAY.
